Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 512.76 g/mol gives Methyl oleanolate acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl oleanolate acetate (CAS 1721-57-9), molecular formula C33H52O4 and molecular weight 512.76 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Methyl oleanolate acetate (C33H52O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 512.76 g/mol, it falls into the moderately-high-molecular-weight range. 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), Methyl oleanolate acetate 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.
