Octyl-3,5-di-tert-butyl-4-hydroxyhydrocinnamate (CAS 125643-61-0) is a high-purity analytical reference standard with the molecular formula C25H42O3 and a molecular weight of 390.60 g/mol.
Octyl-3,5-di-tert-butyl-4-hydroxyhydrocinnamate (C25H42O3) 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), Octyl-3,5-di-tert-butyl-4-hydroxyhydrocinnamate 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.
