Fosfomycin Impurity 63 CAS CATO-C4X-131663

Description

The occurrence of Fosfomycin Impurity 63 is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Fosfomycin Impurity 63 (CAS CATO-C4X-131663) is a certified pharmaceutical impurity reference standard with the molecular formula C7H15O4P and a molecular weight of 194.17 g/mol.

Structurally, Fosfomycin Impurity 63 (C7H15O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 194.17 g/mol, it falls into the medium-molecular-weight range.

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 63 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.
