4-Amino-3-(2-hydroxy-5-methoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione CAS 2494274-01-8

Description

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

4-Amino-3-(2-hydroxy-5-methoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 2494274-01-8) is a high-purity analytical reference standard with the molecular formula C9H10N4O2S and a molecular weight of 238.27 g/mol.

The molecular framework of 4-Amino-3-(2-hydroxy-5-methoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione (C9H10N4O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
