Chemical Structure

1,2,4-Triazolin-3-one CAS 930-33-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2,4-Triazolin-3-one.

CATO supplies 1,2,4-Triazolin-3-one (CAS 930-33-6), a certified reference material (molecular formula C2H3N3O, MW 85.06 g/mol) for analytical method development and quality control.

Owing to an amide group, a hydroxyl group, an ether linkage, 1,2,4-Triazolin-3-one is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 85.06 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.
