Chemical Structure
Description
1-(2-(2,4-Dichlorophenoxy)phenyl)-5-phenyl-1H-1,2,3-triazole-4-carboxylic acid (CAS 664966-03-4) is a high-purity analytical reference standard with the molecular formula C21H13Cl2N3O3 and a molecular weight of 426.25 g/mol.
1-(2-(2,4-Dichlorophenoxy)phenyl)-5-phenyl-1H-1,2,3-triazole-4-carboxylic acid (C21H13Cl2N3O3) contains a steroid core, 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.
