Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 8-(4-isopropylphenyl)-8-oxooctanoate.
Ethyl 8-(4-isopropylphenyl)-8-oxooctanoate (CAS 898778-41-1), molecular formula C19H28O3 and molecular weight 304.42 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 8-(4-isopropylphenyl)-8-oxooctanoate (C19H28O3) contains a steroid core, 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), Ethyl 8-(4-isopropylphenyl)-8-oxooctanoate 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.
