1-(5-Chloro-2-hydroxyphenyl)-3-(m-tolyl)propane-1,3-dione (CAS 420825-19-0), molecular formula C16H13ClO3 and molecular weight 288.73 g/mol, is a CATO reference standard with documented purity and traceability.
1-(5-Chloro-2-hydroxyphenyl)-3-(m-tolyl)propane-1,3-dione (C16H13ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
