Tetrapolyphosphoric acid

CAS 13813-62-2H6O13P4MW 337.94

Tetrapolyphosphoric acid (CAS registry number 13813-62-2) is supplied as a chemical raw material for formulation and synthesis work. The molecular formula is H6O13P4, giving a molecular weight of 337.94 g/mol. This is a inorganic compound of 17 heteroatoms, present in ionic form; 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.

Applications

Organic Chemicals

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.

Packaging & Storage

SampleAvailable on request
Lead TimeIn stock / per order

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

From a process-selection standpoint, This product is inorganic, centred on a metal and is strongly polar and essentially water-soluble. 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.

For this product specifically: an inorganic framework is normally more heat-stable than its organic counterparts, but water content and particle size directly control dissolution rate and batch uniformity. Both are worth measuring at sample stage instead of at scale-up.

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.

How it behaves in your formulation

Strong polarity means it exists as individual molecules in the aqueous phase, so it dissolves directly without any pre-dispersion step. The cost here is not handling but dosage: strongly polar materials often need a lower active addition than their equivalents, so calculate on active content rather than total weight.

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.

Storage, handling and documents

A few points on receipt and storage. keep the container tightly sealed — ionic products readily absorb moisture and cake; 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.

Technical Profile

Tetrapolyphosphoric acid is a carbon-based organic compound with CAS registry number 13813-62-2 and molecular formula H6O13P4 (molecular weight 337.94), 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 Tetrapolyphosphoric acid with stable inventory and provides a Certificate of Analysis (COA) with each batch; custom repacking is available per process requirement.

CAS number: 13813-62-2 — searchable in PubChem for physicochemical, safety and regulatory data.

Its molecular formula H6O13P4 comprises 6 H, 13 O, 4 P atoms.

Also known as: Tetrapolyphosphoric acid

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.

PubChem Public Data

Independent reference data for Tetrapolyphosphoric acid (CAS 13813-62-2), 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.
