Chemical Structure

pregabalin Impurity 36 CAS 181289-16-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 155.19 g/mol gives pregabalin Impurity 36 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies pregabalin Impurity 36 (CAS 181289-16-7), a pharmacopoeial impurity reference standard (molecular formula C8H13NO2, MW 155.19 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, pregabalin Impurity 36 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 155.19 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 36 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.
