5-(4-Chloro-2-methylphenyl)-3-methyl-5-oxovaleric acid CAS 951885-45-3

Description

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

5-(4-Chloro-2-methylphenyl)-3-methyl-5-oxovaleric acid (CAS 951885-45-3) is a high-purity analytical reference standard with the molecular formula C13H15ClO3 and a molecular weight of 254.71 g/mol.

5-(4-Chloro-2-methylphenyl)-3-methyl-5-oxovaleric acid (C13H15ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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.
