Chemical Structure
Description
4-methoxy-2-(3-methylbutoxy)benzoic acid (CAS 1285556-26-4) is a high-purity analytical reference standard with the molecular formula C13H18O4 and a molecular weight of 238.28 g/mol.
4-methoxy-2-(3-methylbutoxy)benzoic acid (C13H18O4) 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.
As a certified reference material (CRM), 4-methoxy-2-(3-methylbutoxy)benzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
