Chemical Structure
Description
3-Bromo-5-isopropyl-1H-1,2,4-triazole (CAS 141831-72-3), molecular formula C5H8BrN3 and molecular weight 190.04 g/mol, is a CATO reference standard with documented purity and traceability.
3-Bromo-5-isopropyl-1H-1,2,4-triazole (C5H8BrN3) contains a nitrile group, 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-Bromo-5-isopropyl-1H-1,2,4-triazole 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.
