Pregabalin Impurity 131 CAS 1568181-40-7 (free base) chemical structure

Description

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 supplies Pregabalin Impurity 131 (CAS 1568181-40-7 (free base)), a pharmacopoeial impurity reference standard (molecular formula C8H18N2OHCl, MW 194.70 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C8H18N2OHCl, Pregabalin Impurity 131 contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 194.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures Pregabalin Impurity 131 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.
