Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(4-Ethyl-5-((4-methylbenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine.
CATO supplies 3-(4-Ethyl-5-((4-methylbenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (CAS 618426-48-5), a certified reference material (molecular formula C17H18N4S, MW 310.42 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 3-(4-Ethyl-5-((4-methylbenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 310.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
