Chemical Structure

(1-Hydroxyethyl)phosphonic acid CAS 20188-02-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1-Hydroxyethyl)phosphonic acid.

(1-Hydroxyethyl)phosphonic acid (CAS 20188-02-7) is a high-purity analytical reference standard with the molecular formula C2H7O4P and a molecular weight of 126.05 g/mol.

Owing to a phosphate ester group, a carboxylic acid group, an ether linkage, (1-Hydroxyethyl)phosphonic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.

CATO manufactures (1-Hydroxyethyl)phosphonic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
