Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 411.86 g/mol gives Gatifloxacin USP RC E HCI distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Gatifloxacin USP RC E HCI (CAS 1219097-41-2) is a high-purity analytical reference standard with the molecular formula C19H22FN3O4HCl and a molecular weight of 411.86 g/mol.
The molecular framework of Gatifloxacin USP RC E HCI (C19H22FN3O4HCl) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Gatifloxacin USP RC E HCI 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.
