Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 317.88 g/mol gives Chlorprothixene EP Impurity B HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Chlorprothixene EP Impurity B HCl (CAS 4907-84-0), a pharmacopoeial impurity reference standard (molecular formula C18H19NSHCl, MW 317.88 g/mol) used for the identification and quantification of trace impurities in APIs.
Chlorprothixene EP Impurity B HCl (C18H19NSHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Chlorprothixene EP Impurity B HCl 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.
