Fosfomycin Impurity 72 CAS 26017-01-6 chemical structure

Description

As a certified reference material (CRM), Fosfomycin Impurity 72 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies Fosfomycin Impurity 72 (CAS 26017-01-6), a pharmacopoeial impurity reference standard (molecular formula C3H5O4PNa, MW 159.03 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a phosphate ester group, a carboxylic acid group, an ether linkage, Fosfomycin Impurity 72 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 159.03 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.
