Chemical Structure
Description
The occurrence of 2-(4-(Ethylsulfonyl)-3-(4-methoxyphenyl)-6-oxopyridazin-1(6H)-yl)acetic acid is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(4-(Ethylsulfonyl)-3-(4-methoxyphenyl)-6-oxopyridazin-1(6H)-yl)acetic acid (CAS 1708269-11-7) is a high-purity analytical reference standard with the molecular formula C15H16N2O6S and a molecular weight of 352.36 g/mol.
The molecular framework of 2-(4-(Ethylsulfonyl)-3-(4-methoxyphenyl)-6-oxopyridazin-1(6H)-yl)acetic acid (C15H16N2O6S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
