3-Hydrazinyl-6-methyl-4H-1,2,4-triazin-5-one CAS 38736-23-1

Description

Owing to an amide group, a hydroxyl group, an ether linkage, 3-Hydrazinyl-6-methyl-4H-1,2,4-triazin-5-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.13 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).

3-Hydrazinyl-6-methyl-4H-1,2,4-triazin-5-one (CAS 38736-23-1), molecular formula C4H7N5O and molecular weight 141.13 g/mol, is a CATO reference standard with documented purity and traceability.

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.
