4-(2,4-Dimethylphenyl)-2,2-dimethyl-4-oxobutanoic acid CAS 951894-22-7

Description

4-(2,4-Dimethylphenyl)-2,2-dimethyl-4-oxobutanoic acid (CAS 951894-22-7), molecular formula C14H18O3 and molecular weight 234.29 g/mol, is a CATO reference standard with documented purity and traceability.

4-(2,4-Dimethylphenyl)-2,2-dimethyl-4-oxobutanoic acid (C14H18O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 4-(2,4-Dimethylphenyl)-2,2-dimethyl-4-oxobutanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
