Fosfomycin Impurity 71 CAS CATO-C4X-131671 chemical structure

Description

Fosfomycin Impurity 71 (CAS CATO-C4X-131671) is a certified pharmaceutical impurity reference standard with the molecular formula C3H8O6P2 and a molecular weight of 202.04 g/mol.

Owing to a phosphate ester group, a carboxylic acid group, an ether linkage, Fosfomycin Impurity 71 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Fosfomycin Impurity 71 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.
