Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2-Ethoxy-3-methoxyphenyl)propanoic acid.
3-(2-Ethoxy-3-methoxyphenyl)propanoic acid (CAS 873422-29-8) is a high-purity analytical reference standard with the molecular formula C12H16O4 and a molecular weight of 224.25 g/mol.
3-(2-Ethoxy-3-methoxyphenyl)propanoic acid (C12H16O4) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
