Chemical Structure
Description
The occurrence of 18-(Benzyloxy)-18-oxooctadecanoic acid is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 18-(Benzyloxy)-18-oxooctadecanoic acid (CAS 189625-51-2), a certified reference material (molecular formula C25H40O4, MW 404.58 g/mol) for analytical method development and quality control.
18-(Benzyloxy)-18-oxooctadecanoic acid (C25H40O4) 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), 18-(Benzyloxy)-18-oxooctadecanoic 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.
