Chemical Structure

(2-Methoxy-2-oxoethyl)phosphonic Acid CAS 40962-37-6 chemical structure

Description

(2-Methoxy-2-oxoethyl)phosphonic Acid (CAS 40962-37-6), molecular formula C3H7O5P and molecular weight 154.06 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (2-Methoxy-2-oxoethyl)phosphonic Acid (C3H7O5P) 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (2-Methoxy-2-oxoethyl)phosphonic Acid 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.
