Chemical Structure
Description
Methyl 5-chloro-2-(1H-1,2,4-triazol-1-yl)benzoate (CAS 1420837-38-2), molecular formula C10H8ClN3O2 and molecular weight 237.64 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 5-chloro-2-(1H-1,2,4-triazol-1-yl)benzoate (C10H8ClN3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
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.
