Chemical Structure

Nemonoxacin Impurity 63 CAS 951163-62-5 chemical structure

Description

The occurrence of Nemonoxacin Impurity 63 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Nemonoxacin Impurity 63 (CAS 951163-62-5), a pharmacopoeial impurity reference standard (molecular formula C11H23NO4, MW 233.30 g/mol) used for the identification and quantification of trace impurities in APIs.

Nemonoxacin Impurity 63 (C11H23NO4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), Nemonoxacin Impurity 63 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.
