Description
CATO manufactures Mirtazapine EP Impurity D 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.
CATO supplies Mirtazapine EP Impurity D HCl (CAS 1188265-41-9), a pharmacopoeial impurity reference standard (molecular formula C16H17N3HCl, MW 287.79 g/mol) used for the identification and quantification of trace impurities in APIs.
Mirtazapine EP Impurity D HCl (C16H17N3HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. 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.
