Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Nemonoxacin Impurity 92 MalicAcid.
As a process- or degradation-related impurity, Nemonoxacin Impurity 92 MalicAcid (CAS CATO-C4X-312892, C20H25N3O4C4H6O5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Nemonoxacin Impurity 92 MalicAcid (C20H25N3O4C4H6O5) contains a flavonoid core, 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.
CATO manufactures Nemonoxacin Impurity 92 MalicAcid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
