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-(6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophen-3-yl)-4H-1,2,4-triazole-3-thiol.
CATO supplies 4-Ethyl-5-(6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophen-3-yl)-4H-1,2,4-triazole-3-thiol (CAS 438231-18-6), a certified reference material (molecular formula C13H17N3S2, MW 279.42 g/mol) for analytical method development and quality control.
Structurally, 4-Ethyl-5-(6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophen-3-yl)-4H-1,2,4-triazole-3-thiol (C13H17N3S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 279.42 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
