Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Amino-5-bromo-4-(trifluoromethyl)thiazole (CAS 136411-21-7), molecular formula C4H2BrF3N2S and molecular weight 247.04 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Amino-5-bromo-4-(trifluoromethyl)thiazole (C4H2BrF3N2S) contains a nitrile group, sulfur-containing functionality, fluorine/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 247.04 g/mol, it falls into the medium-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).
As a certified reference material (CRM), 2-Amino-5-bromo-4-(trifluoromethyl)thiazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
