Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 3-Bromo-5-hydrazinyl-1-methyl-1H-1,2,4-triazole (CAS 1243250-18-1), a certified reference material (molecular formula C3H6BrN5, MW 192.02 g/mol) for analytical method development and quality control.
Structurally, 3-Bromo-5-hydrazinyl-1-methyl-1H-1,2,4-triazole (C3H6BrN5) 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 192.02 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.
