3-(4-Allyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)-1-(4-chlorobenzyl)pyridin-2(1H)-one (CAS 400075-02-7) is a high-purity analytical reference standard with the molecular formula C18H17ClN4OS and a molecular weight of 372.87 g/mol.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 3-(4-Allyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)-1-(4-chlorobenzyl)pyridin-2(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 3-(4-Allyl-5-(methylthio)-4H-1,2,4-triazol-3-yl)-1-(4-chlorobenzyl)pyridin-2(1H)-one 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.
