Description
CATO manufactures 5-bromo-3-chloro-1,2,4-thiadiazole 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 5-bromo-3-chloro-1,2,4-thiadiazole (CAS 213325-82-7), a certified reference material (molecular formula C2H4BrClN2S, MW 203.49 g/mol) for analytical method development and quality control.
The molecular framework of 5-bromo-3-chloro-1,2,4-thiadiazole (C2H4BrClN2S) is characterized by sulfur-containing functionality, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
