Chemical Structure
Description
The occurrence of 5-Bromo-2-chloro-4-(trifluoromethyl)thiazole is closely related to a nitrile group, sulfur-containing functionality, fluorine/chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Bromo-2-chloro-4-(trifluoromethyl)thiazole (CAS 1289049-22-4), molecular formula C4BrClF3NS and molecular weight 266.47 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-2-chloro-4-(trifluoromethyl)thiazole (C4BrClF3NS) contains a nitrile group, sulfur-containing functionality, fluorine/chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 5-Bromo-2-chloro-4-(trifluoromethyl)thiazole 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.
