Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-((4-Chlorophenyl)sulfonyl)-1-(3,4-dimethoxyphenyl)propan-1-one.
3-((4-Chlorophenyl)sulfonyl)-1-(3,4-dimethoxyphenyl)propan-1-one (CAS 720667-92-5), molecular formula C17H17ClO5S and molecular weight 368.83 g/mol, is a CATO reference standard with documented purity and traceability.
3-((4-Chlorophenyl)sulfonyl)-1-(3,4-dimethoxyphenyl)propan-1-one (C17H17ClO5S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
