PIGMENT YELLOW 151

PIGMENT YELLOW 151 (CAS registry number 31837-42-0) is supplied as a chemical raw material for formulation and synthesis work. The molecular formula is C18H15N5O5, giving a molecular weight of 381.3 g/mol. This is a aromatic compound of 18 carbon with 10 heteroatoms, built on a ring-unsaturated carbon skeleton; of medium-to-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.

Product Overview

Applications

Dyes &amp；Pigments

Recorded applications for this entry: Dyes &amp, 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.

Packaging & Storage

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.

Quality & Documentation

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.

Molecular Character — Selection Notes

What the structure means for your process

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.

From a process-selection standpoint, This product is an aromatic organic carrying 5 oxygen, 5 nitrogen, and is close to hydrophilic-lipophilic balance, which suits emulsifying or solubilising work. 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.

How it behaves in your formulation

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.

At 320~500 g/mol the species exists in water as a colloid or polymer segments and measurably changes rheology once dispersed, making it useful as a thickener, dispersant, film former or release matrix. Check shear stability separately — a wide molecular-weight distribution can lose viscosity faster than expected under strong shear.

A balanced hydrophilic-lipophilic profile is exactly what an emulsified system needs. The molecule partitions freely between the two phases, which makes it the connecting component that removes the need for a solvent bridge.

Storage, handling and documents

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.

A few points on receipt and storage. control dust and wear eye protection, as the material can irritate mucous membranes; 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.

Technical Profile

What this product is

PIGMENT YELLOW 151 is a colorant or pigment compound with CAS registry number 31837-42-0 and molecular formula C18H15N5O5 (molecular weight 381.3), 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.

PIGMENT YELLOW 151 is typically applied in Dyes &amp, Pigments.

Jinan Shenghe Chemical Co., Ltd. supplies PIGMENT YELLOW 151 with stable inventory and provides a Certificate of Analysis (COA) with each batch; custom repacking is available per process requirement.

Identification

CAS number: 31837-42-0 — searchable in PubChem for physicochemical, safety and regulatory data.

Its molecular formula C18H15N5O5 comprises 18 C, 15 H, 5 N, 5 O atoms.

Also known as: PIGMENT YELLOW 151

Category: dyes and pigments

Applications and qualification

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 &amp, 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.

Specification and documentation

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.

Sourcing and supply

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.
