(E)-N-(2-(3-methyl-4-nitroisoxazol-5-yl)vinyl)-4-(trifluoromethoxy)aniline CAS 338402-61-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 329.23 g/mol gives (E)-N-(2-(3-methyl-4-nitroisoxazol-5-yl)vinyl)-4-(trifluoromethoxy)aniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(E)-N-(2-(3-methyl-4-nitroisoxazol-5-yl)vinyl)-4-(trifluoromethoxy)aniline (CAS 338402-61-2) is a high-purity analytical reference standard with the molecular formula C13H10F3N3O4 and a molecular weight of 329.23 g/mol.

The molecular framework of (E)-N-(2-(3-methyl-4-nitroisoxazol-5-yl)vinyl)-4-(trifluoromethoxy)aniline (C13H10F3N3O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
