Description
CATO manufactures 2,4,5-Tribromo-1-methylimidazole 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.
2,4,5-Tribromo-1-methylimidazole (CAS 1003-91-4), molecular formula C4H3Br3N2 and molecular weight 318.79 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,4,5-Tribromo-1-methylimidazole (C4H3Br3N2) contains a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 318.79 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
