Pregabalin impurity 91 CAS 159029-27-3 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 91 (CAS 159029-27-3), a pharmacopoeial impurity reference standard (molecular formula C7H18N2HCl, MW 166.69 g/mol) used for the identification and quantification of trace impurities in APIs.

Pregabalin impurity 91 (C7H18N2HCl) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures Pregabalin impurity 91 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.
