Zolpidem Impurity N16 CAS 768398-03-4 chemical structure

Description

CATO manufactures Zolpidem Impurity N16 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.

As a process- or degradation-related impurity, Zolpidem Impurity N16 (CAS 768398-03-4, C17H15N3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Zolpidem Impurity N16 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 261.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
