Chemical Structure
Description
3-(Bromomethyl)isothiazole (CAS 4576-91-4), molecular formula C4H4BrNS and molecular weight 178.05 g/mol, is a CATO reference standard with documented purity and traceability.
3-(Bromomethyl)isothiazole (C4H4BrNS) contains a nitrile group, sulfur-containing functionality, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3-(Bromomethyl)isothiazole 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.
