Chemical Structure
Description
2,3-dichloro-3-[(4-methoxybenzyl)sulfinyl]-N-(6-methoxy-3-pyridinyl)acrylamide (CAS 337922-28-8) is a high-purity analytical reference standard with the molecular formula C17H16Cl2N2O4S and a molecular weight of 415.29 g/mol.
2,3-dichloro-3-[(4-methoxybenzyl)sulfinyl]-N-(6-methoxy-3-pyridinyl)acrylamide (C17H16Cl2N2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 2,3-dichloro-3-[(4-methoxybenzyl)sulfinyl]-N-(6-methoxy-3-pyridinyl)acrylamide 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.
