Chemical Structure
Description
4-Diisopropylamino-2-phenyl-butyric acid ethyl ester (CAS 214601-79-3) is a high-purity analytical reference standard with the molecular formula C18H29NO2 and a molecular weight of 291.43 g/mol.
4-Diisopropylamino-2-phenyl-butyric acid ethyl ester (C18H29NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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-Diisopropylamino-2-phenyl-butyric acid ethyl ester 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.
