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-tert-butylphenyl)methyl]sulfanyl}-4-ethyl-5-{thieno[2,3-b]quinolin-2-yl}-4H-1,2,4-triazole.
3-{[(4-tert-butylphenyl)methyl]sulfanyl}-4-ethyl-5-{thieno[2,3-b]quinolin-2-yl}-4H-1,2,4-triazole (CAS 439112-38-6), molecular formula C26H26N4S2 and molecular weight 458.64 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 3-{[(4-tert-butylphenyl)methyl]sulfanyl}-4-ethyl-5-{thieno[2,3-b]quinolin-2-yl}-4H-1,2,4-triazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 458.64 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.
CATO manufactures 3-{[(4-tert-butylphenyl)methyl]sulfanyl}-4-ethyl-5-{thieno[2,3-b]quinolin-2-yl}-4H-1,2,4-triazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
