Chemical Structure
Description
Structurally, Fosfomycin Trometamol EP Impurity A Di-Ammonium Salt (C3H9O5PH3N) contains an amide group, a phosphate ester group, a carboxylic acid group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -1.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 173.11 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a process- or degradation-related impurity, Fosfomycin Trometamol EP Impurity A Di-Ammonium Salt (CAS CATO-C4X-131612, C3H9O5PH3N) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical 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.
