Chemical Structure
Description
The occurrence of (E)-2-(4-chlorophenyl)-N-((methoxyimino)methyl)-2-(3-(trifluoromethyl)quinoxalin-2-yl)acetamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(E)-2-(4-chlorophenyl)-N-((methoxyimino)methyl)-2-(3-(trifluoromethyl)quinoxalin-2-yl)acetamide (CAS 338412-29-6) is a high-purity analytical reference standard with the molecular formula C19H14ClF3N4O2 and a molecular weight of 422.79 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (E)-2-(4-chlorophenyl)-N-((methoxyimino)methyl)-2-(3-(trifluoromethyl)quinoxalin-2-yl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 422.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (E)-2-(4-chlorophenyl)-N-((methoxyimino)methyl)-2-(3-(trifluoromethyl)quinoxalin-2-yl)acetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
