Moxifloxacin Impurity 90 CAS 765-30-0

Description

The occurrence of Moxifloxacin Impurity 90 is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Moxifloxacin Impurity 90 (CAS 765-30-0), a pharmacopoeial impurity reference standard (molecular formula C3H7N, MW 57.09 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Moxifloxacin Impurity 90 (C3H7N) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

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.
