Fosfomycin Impurity 70 CAS CATO-C4X-131670 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 70.

Fosfomycin Impurity 70 (CAS CATO-C4X-131670) is a certified pharmaceutical impurity reference standard with the molecular formula C19H40O6P2 and a molecular weight of 426.46 g/mol.

The molecular framework of Fosfomycin Impurity 70 (C19H40O6P2) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.

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.
