Chemical Structure
Description
CATO supplies 4-(Benzo[d]thiazol-2-ylthio)-3-chloroaniline (CAS 300809-71-6), a certified reference material (molecular formula C13H9ClN2S2, MW 292.81 g/mol) for analytical method development and quality control.
4-(Benzo[d]thiazol-2-ylthio)-3-chloroaniline (C13H9ClN2S2) 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4-(Benzo[d]thiazol-2-ylthio)-3-chloroaniline 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.
