Chemical Structure

Fosfomycin Impurity 56 CAS CATO-C4X-131656 chemical structure

Description

CATO supplies Fosfomycin Impurity 56 (CAS CATO-C4X-131656), a pharmacopoeial impurity reference standard (molecular formula C4H11O5P, MW 170.10 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C4H11O5P, Fosfomycin Impurity 56 contains a carbohydrate-derived structure, a phosphate ester group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 170.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.

As a certified reference material (CRM), Fosfomycin Impurity 56 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.
