diethyl (tosyloxy)methylphosphonate

diethyl (tosyloxy)methylphosphonate (CAS registry number 31618-90-3) is supplied as a chemical raw material for formulation and synthesis work. The molecular formula is C12H19O6PS, giving a molecular weight of 322.32 g/mol. This is a polyfunctional organic compound of 12 carbon with 8 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.

Product Overview

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

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

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 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 6 oxygen, 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

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. 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.

Technical Profile

diethyl (tosyloxy)methylphosphonate is a carbon-based organic compound with CAS registry number 31618-90-3 and molecular formula C12H19O6PS (molecular weight 322.32), 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 diethyl (tosyloxy)methylphosphonate with stable inventory and provides a Certificate of Analysis (COA) with each batch; custom repacking is available per process requirement.

CAS number: 31618-90-3 — searchable in PubChem for physicochemical, safety and regulatory data.

Its molecular formula C12H19O6PS comprises 12 C, 19 H, 6 O, 1 P, 1 S atoms.

Also known as: diethyl (tosyloxy)methylphosphonate

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.
