Chemical Structure

Trimethylphosphate CAS 512-56-1 chemical structure

Description

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

Trimethylphosphate (CAS 512-56-1), molecular formula C3H9O4P and molecular weight 140.07 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Trimethylphosphate (C3H9O4P) is characterized by a phosphate ester group, a carboxylic acid group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

As a certified reference material (CRM), Trimethylphosphate 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.
