Chemical Structure

Phosphonoacetic acid CAS 4408-78-0 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.

CATO supplies Phosphonoacetic acid (CAS 4408-78-0), a certified reference material (molecular formula C2H5O5P, MW 140.03 g/mol) for analytical method development and quality control.

The molecular framework of Phosphonoacetic acid (C2H5O5P) 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
