Chemical Structure

Fosfomycin Impurity 77 CAS 13563-34-3 chemical structure

Description

The occurrence of Fosfomycin Impurity 77 is closely related to a phosphate ester group, a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Fosfomycin Impurity 77 (CAS 13563-34-3) is a certified pharmaceutical impurity reference standard with the molecular formula C3H9O5P and a molecular weight of 156.07 g/mol.

Based on its molecular formula C3H9O5P, Fosfomycin Impurity 77 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 156.07 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.

CATO manufactures Fosfomycin Impurity 77 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.
