1-(2,4-Difluorobenzyl)-5-ethyl-1H-1,2,3-triazole-4-carboxylic acid CAS 1273926-41-2

Description

The occurrence of 1-(2,4-Difluorobenzyl)-5-ethyl-1H-1,2,3-triazole-4-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(2,4-Difluorobenzyl)-5-ethyl-1H-1,2,3-triazole-4-carboxylic acid (CAS 1273926-41-2), molecular formula C12H11F2N3O2 and molecular weight 267.23 g/mol, is a CATO reference standard with documented purity and traceability.

1-(2,4-Difluorobenzyl)-5-ethyl-1H-1,2,3-triazole-4-carboxylic acid (C12H11F2N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
