2-(4-Ethyl-5-((naphthalen-1-ylmethyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (CAS 578719-50-3) is a high-purity analytical reference standard with the molecular formula C20H18N4S and a molecular weight of 346.45 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 2-(4-Ethyl-5-((naphthalen-1-ylmethyl)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 346.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 2-(4-Ethyl-5-((naphthalen-1-ylmethyl)thio)-4H-1,2,4-triazol-3-yl)pyridine 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.
