Chemical Structure

Moxifloxacin Impurity 152 CAS 1932592-78-3 chemical structure

Description

The occurrence of Moxifloxacin Impurity 152 is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Moxifloxacin Impurity 152 (CAS 1932592-78-3) is a certified pharmaceutical impurity reference standard with the molecular formula C9H18N2 and a molecular weight of 154.25 g/mol.

The molecular framework of Moxifloxacin Impurity 152 (C9H18N2) is characterized by a nitrile group. 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.

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.
