Chemical Structure

Pregabalin Impurity 129 CAS 1262340-21-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 186.25 g/mol gives Pregabalin Impurity 129 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Pregabalin Impurity 129 (CAS 1262340-21-5, C9H18N2O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Pregabalin Impurity 129 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.25 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.

CATO manufactures Pregabalin Impurity 129 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.
