Description
As a certified reference material (CRM), (5-bromo-2-methyl-1,2,4-triazol-3-yl)methanol 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.
(5-bromo-2-methyl-1,2,4-triazol-3-yl)methanol (CAS 1780630-08-1), molecular formula C4H6BrN3O and molecular weight 192.01 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (5-bromo-2-methyl-1,2,4-triazol-3-yl)methanol (C4H6BrN3O) contains an amide group, a hydroxyl group, an ether linkage, 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 192.01 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
