Chemical Structure
Description
The occurrence of 7-(Thiophen-2-yl)-2h,3h-[1,4]dioxino[2,3-g]quinoline-9-carboxylic 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.
CATO supplies 7-(Thiophen-2-yl)-2h,3h-[1,4]dioxino[2,3-g]quinoline-9-carboxylic acid (CAS 847508-31-0), a certified reference material (molecular formula C16H11NO4S, MW 313.33 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 7-(Thiophen-2-yl)-2h,3h-[1,4]dioxino[2,3-g]quinoline-9-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 313.33 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).
