Chemical Structure
Description
The occurrence of (+)-[12S,13r]-epoxy-cis-9-octadecenoicacidmethylester is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(+)-[12S,13r]-epoxy-cis-9-octadecenoicacidmethylester (CAS 2733-91-7), molecular formula C19H34O3 and molecular weight 310.47 g/mol, is a CATO reference standard with documented purity and traceability.
(+)-[12S,13r]-epoxy-cis-9-octadecenoicacidmethylester (C19H34O3) contains a carboxylic acid 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), (+)-[12S,13r]-epoxy-cis-9-octadecenoicacidmethylester 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.
