Chemical Structure

Pregabalin Impurity 60 CAS 181289-33-8 chemical structure

Description

CATO manufactures Pregabalin Impurity 60 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.

CATO supplies Pregabalin Impurity 60 (CAS 181289-33-8), a pharmacopoeial impurity reference standard (molecular formula C9H17NO3, MW 187.24 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 60 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 187.24 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.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
