Chemical Structure

Fosfomycin Impurity 52 HCl CAS 3031788-32-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 171.62 g/mol gives Fosfomycin Impurity 52 HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Fosfomycin Impurity 52 HCl (CAS 3031788-32-3), a pharmacopoeial impurity reference standard (molecular formula C5H13NO3HCl, MW 171.62 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C5H13NO3HCl, Fosfomycin Impurity 52 HCl contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 171.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
