Chemical Structure
Description
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.
Ethyl (Z)-3-((3,4-difluorophenyl)amino)-2-((3,5-dimethylphenyl)sulfonyl)acrylate (CAS 1327179-39-4) is a high-purity analytical reference standard with the molecular formula C19H19F2NO4S and a molecular weight of 395.42 g/mol.
Ethyl (Z)-3-((3,4-difluorophenyl)amino)-2-((3,5-dimethylphenyl)sulfonyl)acrylate (C19H19F2NO4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures Ethyl (Z)-3-((3,4-difluorophenyl)amino)-2-((3,5-dimethylphenyl)sulfonyl)acrylate 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.
