2-Butenoic acid, 3-amino-4,4,4-trichloro-2-cyano-, ethyl ester 22071-00-7 CTK0J6769 (CAS 22071-00-7) is a high-purity analytical reference standard with the molecular formula C7H7Cl3N2O2 and a molecular weight of 257.50 g/mol.
2-Butenoic acid, 3-amino-4,4,4-trichloro-2-cyano-, ethyl ester 22071-00-7 CTK0J6769 (C7H7Cl3N2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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 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.
