Fosfomycin Impurity 83 CAS 6913-02-6 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 Fosfomycin Impurity 83.

CATO supplies Fosfomycin Impurity 83 (CAS 6913-02-6), a pharmacopoeial impurity reference standard (molecular formula C3H7O4P, MW 138.06 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C3H7O4P, Fosfomycin Impurity 83 contains a phosphate ester group, a carboxylic acid group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 138.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

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.
