[5-(3-Trifluoromethyl-phenyl)-[1,2,4]oxadiazol-3-yl]-acetic acid ethyl ester CAS 1208081-92-8

Description

The occurrence of [5-(3-Trifluoromethyl-phenyl)-[1,2,4]oxadiazol-3-yl]-acetic acid ethyl ester 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.

[5-(3-Trifluoromethyl-phenyl)-[1,2,4]oxadiazol-3-yl]-acetic acid ethyl ester (CAS 1208081-92-8) is a high-purity analytical reference standard with the molecular formula C13H11F3N2O3 and a molecular weight of 300.23 g/mol.

[5-(3-Trifluoromethyl-phenyl)-[1,2,4]oxadiazol-3-yl]-acetic acid ethyl ester (C13H11F3N2O3) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
