undecane-2,3-dione (CAS registry number 7493-59-6) is supplied as a chemical raw material for formulation and synthesis work. The molecular formula is C11H20O2, giving a molecular weight of 184.27 g/mol. This is a organic compound of 11 carbon with 2 heteroatoms, predominantly aliphatic; of low 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.

Recorded applications for this entry: Organic Chemicals. 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.

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.
For this product specifically: the saturated aliphatic backbone is stable at ambient conditions, so oxidation risk comes mainly from oxygen, peroxides or trace transition metals introduced in processing rather than from the skeleton itself. If oxidisable components are also present, evaluate the order of addition during storage.
From a process-selection standpoint, This product is an aliphatic organic carrying 2 oxygen, and leans lipophilic, preferring the organic phase. 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.
At 120~200 g/mol, this is the most common scale in fine chemicals, balancing reactivity with handling. It works as a pharmaceutical intermediate, food additive, personal-care ingredient or functional auxiliary, and at this size supply is mature and specification availability is generally good.
Lipophilic character means it prefers the oil phase. In a predominantly aqueous formulation it will form discrete droplets and reduce stability, so emulsification or pre-dissolution in a compatible solvent is normally required. Confirm this at trial stage — creaming in the finished product is far harder to trace back.
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. pre-dissolve lipophilic material in a compatible solvent before introducing it to the aqueous phase; 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.
undecane-2,3-dione is a carbon-based organic compound with CAS registry number 7493-59-6 and molecular formula C11H20O2 (molecular weight 184.27), belonging to the organic chemicals segment of chemical raw materials.
This entry belongs to the organic chemicals 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.
Jinan Shenghe Chemical Co., Ltd. supplies undecane-2,3-dione with stable inventory and provides a Certificate of Analysis (COA) with each batch; custom repacking is available per process requirement.
CAS number: 7493-59-6 — searchable in PubChem for physicochemical, safety and regulatory data.
Its molecular formula C11H20O2 comprises 11 C, 20 H, 2 O atoms.
Also known as: undecane-2,3-dione
Category: organic chemicals
Within the organic chemicals 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.
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 undecane-2,3-dione (CAS 7493-59-6), 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.
