4-Ethyl-5-(4-methoxyphenyl)-4H-1,2,4-triazole-3-thiol CAS 168968-58-9

Description

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

4-Ethyl-5-(4-methoxyphenyl)-4H-1,2,4-triazole-3-thiol (CAS 168968-58-9) is a high-purity analytical reference standard with the molecular formula C11H13N3OS and a molecular weight of 235.31 g/mol.

4-Ethyl-5-(4-methoxyphenyl)-4H-1,2,4-triazole-3-thiol (C11H13N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
