3-Chlorobenzyl 1-(2-methoxyphenyl)-5-methyl-1H-1,2,3-triazole-4-carboxylate (CAS 1040636-19-8), molecular formula C18H16ClN3O3 and molecular weight 357.79 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Chlorobenzyl 1-(2-methoxyphenyl)-5-methyl-1H-1,2,3-triazole-4-carboxylate (C18H16ClN3O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
