C.I. Acid Red 182 (CAS registry number 61901-42-6) is supplied as a chemical raw material for formulation and synthesis work. The molecular formula is C32H23CoN6O8S2, giving a molecular weight of 742.6 g/mol. This is a aromatic compound of 32 carbon with 16 heteroatoms with Co as the metal centre, present in ionic form; of high molecular weight. Documents are issued per shipment rather than per catalogue entry: each batch is accompanied by a Certificate of Analysis, and safety data sheets, technical datasheets and third-party test reports are supplied on request for export documentation.

Dyes &；Pigments
Recorded applications for this entry: Dyes &, Pigments. Where your formulation differs, the relevant point to check is not the use category but the impurity profile — tell us the end use and we will map it to the specification.
For export enquiries, include the destination country and the intended application in your message. This lets us confirm whether the grade needs any additional documentation beyond the standard per-batch COA, and whether the packing suits the planned transport mode.
Packing is per order / batch confirmation (not published) and purity is per batch COA (not published). Both are agreed at order stage; for export movements the packing is chosen with the transport mode and destination in mind, and drum, bag or repacked formats are all available. Storage: sealed, in a cool and dry place, away from direct sunlight.
Each shipment is accompanied by a batch Certificate of Analysis. For cross-border orders, MSDS, technical datasheets and third-party test reports can be issued to match your documentation set; declare the destination country when you enquire so the paperwork matches on arrival. Contact: info@591daili.com · +86-18553102138.
COA (Certificate of Analysis) is provided with every batch. MSDS/technical data sheets and third-party test reports are available on request. Purity and packaging are subject to batch COA and order confirmation.
From a process-selection standpoint, This product is an aromatic organic carrying 8 oxygen, 6 nitrogen, with mid-range polarity. defines where this material fits and where it does not. Three points deserve checking before purchase: structural type, which sets the reactive sites and compatibility; polarity class, which dictates the solvent system; and molecular-weight range, which governs dosage and dispersion feasibility.
Ionic form also carries a hidden cost in selection: hygroscopicity. When sealing is inadequate, ionic inorganic or carboxylate products cake, which affects dosing as well as weighing accuracy. Where the usage rate is low, smaller packs replenished frequently are often cheaper than one large pack held in storage.
For this product specifically: the ring backbone gives better heat and chemical stability than an aliphatic equivalent of equal carbon count, but aromatic systems oxidise and discolour readily at elevated temperature. If your process holds a hot section, run a thermal-stability comparison at the sample stage rather than discovering it in production.
Polarity sits in the conventional range, so behaviour in a given formulation depends on the solvent system and additive interactions around it. A small-scale trial under real formulation conditions is the sensible confirmation.
If you are evaluating this as an alternative to an incumbent supplier, the difficulty for aromatic products is rarely the main component but the impurity profile. The stated impurity distribution may differ from what the incumbent actually delivers, so comparing two or three sample batches before switching is faster than chasing a deviation afterwards.
Above 500 g/mol this sits in the high-molecular-weight range, present as micelles, polymer solution or dispersed phase rather than dissolved molecules, so its function is structural. Confirm degree of shear thinning and batch-to-batch molecular-weight consistency, since both determine whether your finished product stays consistent.
A few points on receipt and storage. keep the container tightly sealed — ionic products readily absorb moisture and cake; control dust and wear eye protection, as the material can irritate mucous membranes; keep inorganic material away from strong acids and reducing agents; pre-disperse high-molecular-weight material, as adding it dry into a viscous medium clumps; specific handling and PPE follow the MSDS issued with the batch.. For inbound or outbound shipments, confirm packing group and transport classification in advance to avoid demurrage caused by documentation mismatch.
On documentation: the batch COA travels with every shipment; MSDS, technical datasheets and third-party test reports can be issued on request. If your quality system requires supplier qualification documents — business licence, production permit, management-system certificates — state the destination country and the document list when you enquire, and we will assemble the set at once.
C.I. Acid Red 182 is a colorant or pigment compound with CAS registry number 61901-42-6 and molecular formula C32H23CoN6O8S2 (molecular weight 742.6), belonging to the dyes and pigments segment of chemical raw materials.
This entry belongs to the dyes and pigments range, where the material is normally supplied against a stated grade rather than blended to a formula. Where a buyer works to a published standard, the useful conversation is about which data the grade is qualified against and how deviations are handled, rather than about the use category itself.
C.I. Acid Red 182 is typically applied in Dyes &, Pigments.
Jinan Shenghe Chemical Co., Ltd. supplies C.I. Acid Red 182 with stable inventory and provides a Certificate of Analysis (COA) with each batch; custom repacking is available per process requirement.
CAS number: 61901-42-6 — searchable in PubChem for physicochemical, safety and regulatory data.
Its molecular formula C32H23CoN6O8S2 comprises 32 C, 23 H, 1 Co, 6 N, 8 O, 2 S atoms.
Also known as: C.I. Acid Red 182
Category: dyes and pigments
Within the dyes and pigments segment, the technical questions differ from other categories. Buyers here are usually working to a specification or a standard rather than to a general description, so the useful conversation covers impurity profile, particle size or assay method, and which data the grade is qualified against.
Application terms recorded for this entry: Dyes &, Pigments. If your specification differs, the point to check is not the use category but the impurity limits — send us the standard you work to and we will confirm what can be supplied against it.
For qualification work, we can supply a sample batch with full documentation so that incoming QC has something concrete to compare against. Mentioning the destination country at enquiry stage also lets us match the paperwork set to your import requirements.
Purity available is per batch COA (not published), with packing per order / batch confirmation (not published). Neither value is asserted in advance: every batch ships with a Certificate of Analysis carrying the measured results, so incoming QC compares against real data rather than a catalogue claim. MSDS, technical datasheets and third-party test reports can be issued for qualification purposes — state the standard you qualify against when you enquire.
Supplier: Jinan Shenghe Chemical Co., Ltd.. For export orders, state the destination country, the transport mode and the document set you need when you enquire — packing, paperwork and quotation terms all follow from those three. Samples can be arranged for qualification, and lead time depends on stock and order size rather than on a fixed promise.

Independent reference data for C.I. Acid Red 182 (CAS 61901-42-6), compiled from public chemistry databases. It is reproduced here so that a qualification decision does not depend on a single source: if your incoming specification and these values disagree, the difference is usually a measurement basis rather than an error. We would rather you saw the same reference figures we do. Values that vary by batch — assay, moisture, particle size, packaging, shelf life — are deliberately excluded and issued on the batch COA instead.
