2-(4-Ethoxyphenyl)-3-methylbutanoic acid (CAS 102270-89-3) is a high-purity analytical reference standard with the molecular formula C13H18O3 and a molecular weight of 222.28 g/mol.
2-(4-Ethoxyphenyl)-3-methylbutanoic acid (C13H18O3) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
