(3aR,6E,10Z,14E,15aS)-6,14-Dimethyl-3-methylene-2-oxo-2,3,3a,4,5,8,9,12,13,15a-decahydrocyclotetradeca[b]furan-10-carboxylic acid (CAS 59632-76-7) is a high-purity analytical reference standard with the molecular formula C20H26O4 and a molecular weight of 330.42 g/mol.
Structurally, (3aR,6E,10Z,14E,15aS)-6,14-Dimethyl-3-methylene-2-oxo-2,3,3a,4,5,8,9,12,13,15a-decahydrocyclotetradeca[b]furan-10-carboxylic acid (C20H26O4) contains a flavonoid core, a hydroxyl group, an ether linkage. 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 330.42 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
