Chemical Structure
Description
As a certified reference material (CRM), 11alpha,12alpha-Epoxy-3beta,13-dihydroxyoleanane-28-oic acid gamma-lactone 19897-41-7 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.
11alpha,12alpha-Epoxy-3beta,13-dihydroxyoleanane-28-oic acid gamma-lactone 19897-41-7 (CAS 19897-41-7) is a high-purity analytical reference standard with the molecular formula C30H46O4 and a molecular weight of 470.68 g/mol.
11alpha,12alpha-Epoxy-3beta,13-dihydroxyoleanane-28-oic acid gamma-lactone 19897-41-7 (C30H46O4) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
