Methyl (3-bromo-5-hydroxy-1H-1,2,4-triazol-1-yl)acetate CAS 1674389-82-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 236.02 g/mol gives Methyl (3-bromo-5-hydroxy-1H-1,2,4-triazol-1-yl)acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl (3-bromo-5-hydroxy-1H-1,2,4-triazol-1-yl)acetate (CAS 1674389-82-2), molecular formula C5H6BrN3O3 and molecular weight 236.02 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Methyl (3-bromo-5-hydroxy-1H-1,2,4-triazol-1-yl)acetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 236.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
