Description

32435-46-4 Q422H5264W Bis(2-(methacryloyloxy)ethyl) phosphate Bis(methacryloyloxyethyl) hydrogen phosphate 2-Propenoic acid, 2-methyl-, 1,1'-(phosphinicobis(oxy-2,1-ethanediyl)) ester 2-Propenoic acid, 2-methyl-, phosphinicobis(oxy-2,1-ethanediyl) ester EINECS 251-040-2 UNII-Q422H5264W (CAS 32435-46-4), molecular formula C12H19O8P and molecular weight 322.25 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 32435-46-4 Q422H5264W Bis(2-(methacryloyloxy)ethyl) phosphate Bis(methacryloyloxyethyl) hydrogen phosphate 2-Propenoic acid, 2-methyl-, 1,1'-(phosphinicobis(oxy-2,1-ethanediyl)) ester 2-Propenoic acid, 2-methyl-, phosphinicobis(oxy-2,1-ethanediyl) ester EINECS 251-040-2 UNII-Q422H5264W (C12H19O8P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 322.25 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 32435-46-4 Q422H5264W Bis(2-(methacryloyloxy)ethyl) phosphate Bis(methacryloyloxyethyl) hydrogen phosphate 2-Propenoic acid, 2-methyl-, 1,1'-(phosphinicobis(oxy-2,1-ethanediyl)) ester 2-Propenoic acid, 2-methyl-, phosphinicobis(oxy-2,1-ethanediyl) ester EINECS 251-040-2 UNII-Q422H5264W meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
