Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2s,4r)-1-(4-Fluorobenzenesulfonyl)-4-hydroxypyrrolidine-2-carboxylic acid.
(2s,4r)-1-(4-Fluorobenzenesulfonyl)-4-hydroxypyrrolidine-2-carboxylic acid (CAS 1613637-25-4), molecular formula C11H12FNO5S and molecular weight 289.28 g/mol, is a CATO reference standard with documented purity and traceability.
(2s,4r)-1-(4-Fluorobenzenesulfonyl)-4-hydroxypyrrolidine-2-carboxylic acid (C11H12FNO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
