Chemical Structure

Sivelestat Impurity 19 CAS 612-34-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 256.26 g/mol gives Sivelestat Impurity 19 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Sivelestat Impurity 19 (CAS 612-34-0, C14H12N2O3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Based on its molecular formula C14H12N2O3, Sivelestat Impurity 19 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 256.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Sivelestat Impurity 19 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.
