3-(4-Methoxyphenyl)-4-methyl-5-(methylthio)-4H-1,2,4-triazole CAS 57295-61-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(4-Methoxyphenyl)-4-methyl-5-(methylthio)-4H-1,2,4-triazole.

3-(4-Methoxyphenyl)-4-methyl-5-(methylthio)-4H-1,2,4-triazole (CAS 57295-61-1) is a high-purity analytical reference standard with the molecular formula C11H13N3OS and a molecular weight of 235.31 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 3-(4-Methoxyphenyl)-4-methyl-5-(methylthio)-4H-1,2,4-triazole is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 235.31 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.
