1-(5-Chloro-2-hydroxy-4-methylphenyl)-3-phenyl-1,3-propanedione CAS 5067-23-2

Description

The occurrence of 1-(5-Chloro-2-hydroxy-4-methylphenyl)-3-phenyl-1,3-propanedione is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(5-Chloro-2-hydroxy-4-methylphenyl)-3-phenyl-1,3-propanedione (CAS 5067-23-2), molecular formula C16H13ClO3 and molecular weight 288.73 g/mol, is a CATO reference standard with documented purity and traceability.

1-(5-Chloro-2-hydroxy-4-methylphenyl)-3-phenyl-1,3-propanedione (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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
