Description
CATO manufactures 6,7-Dichlorobenzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one 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 6,7-Dichlorobenzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one (CAS 866144-64-1), a certified reference material (molecular formula C9H4Cl2N2OS, MW 259.11 g/mol) for analytical method development and quality control.
6,7-Dichlorobenzo[4,5]imidazo[2,1-b]thiazol-3(2H)-one (C9H4Cl2N2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
