Chemical Structure
Description
The occurrence of 6-(Methylsulfonyl)quinoline-3-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, 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.
6-(Methylsulfonyl)quinoline-3-carboxylic acid (CAS 1956366-84-9) is a high-purity analytical reference standard with the molecular formula C11H9NO4S and a molecular weight of 251.26 g/mol.
6-(Methylsulfonyl)quinoline-3-carboxylic acid (C11H9NO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
