Chemical Structure
Description
Isopropyl 2-((4-ethyl-5-(m-tolyl)-4H-1,2,4-triazol-3-yl)thio)acetate (CAS 338428-58-3) is a high-purity analytical reference standard with the molecular formula C16H21N3O2S and a molecular weight of 319.42 g/mol.
Isopropyl 2-((4-ethyl-5-(m-tolyl)-4H-1,2,4-triazol-3-yl)thio)acetate (C16H21N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
