Chemical Structure

Dimethyl Phosphate CAS 813-78-5 chemical structure

Description

The occurrence of Dimethyl Phosphate is closely related to a phosphate ester group, a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Dimethyl Phosphate (CAS 813-78-5) is a high-purity analytical reference standard with the molecular formula C2H7O4P and a molecular weight of 126.05 g/mol.

Dimethyl Phosphate (C2H7O4P) contains a phosphate ester group, a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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), Dimethyl Phosphate 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.
