Chemical Structure
Description
The occurrence of Olean-12-eno[3,2-c]isoxazol-28-oic acid methyl ester, 97% is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Olean-12-eno[3,2-c]isoxazol-28-oic acid methyl ester, 97% (CAS 42273-05-2), a certified reference material (molecular formula C32H47NO3, MW 493.72 g/mol) for analytical method development and quality control.
Olean-12-eno[3,2-c]isoxazol-28-oic acid methyl ester, 97% (C32H47NO3) contains a nitrogen-containing heterocyclic scaffold, 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), Olean-12-eno[3,2-c]isoxazol-28-oic acid methyl ester, 97% 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.
