Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 345.63 g/mol gives Triclabendazole EP Impurity B distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Triclabendazole EP Impurity B (CAS 68828-69-3), a pharmacopoeial impurity reference standard (molecular formula C13H7Cl3N2, MW 345.63 g/mol) used for the identification and quantification of trace impurities in APIs.
Triclabendazole EP Impurity B (C13H7Cl3N2) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Triclabendazole EP Impurity B 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.
