Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, Buspirone impurity 29 HBr is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 366.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies Buspirone impurity 29 HBr (CAS CATO-C4X-125829), a pharmacopoeial impurity reference standard (molecular formula C11H17BrN4HBr, MW 366.10 g/mol) used for the identification and quantification of trace impurities in APIs.
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 Buspirone impurity 29 HBr 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.
