Chemical Structure

Fosfomycin Impurity 55 CAS 50577-86-1 chemical structure

Description

The occurrence of Fosfomycin Impurity 55 is closely related to a phosphate ester group, a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Fosfomycin Impurity 55 (CAS 50577-86-1) is a certified pharmaceutical impurity reference standard with the molecular formula C3H7O4P and a molecular weight of 138.06 g/mol.

Structurally, Fosfomycin Impurity 55 (C3H7O4P) contains a phosphate ester group, a carboxylic acid 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 138.06 g/mol, it falls into the low-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.

As a certified reference material (CRM), Fosfomycin Impurity 55 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.
