Chemical Structure

Pregabalin Impurity 147 CAS CATO-C4X-1312147 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Pregabalin Impurity 147.

CATO supplies Pregabalin Impurity 147 (CAS CATO-C4X-1312147), a pharmacopoeial impurity reference standard (molecular formula C9H17NO2, MW 171.24 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 147 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 171.24 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.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
