Description

Compared with other compounds in its class, the molecular weight of 402.57 g/mol gives (3aR,5E,7S,10E,14E,16aS)-2,7-Dihydroxy-3-((S)-1-hydroxypropan-2-yl)-6,10,14,16a-tetramethyl-3a,4,8,9,12,13,16,16a-octahydrocyclopenta[15]annulen-1(7H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (3aR,5E,7S,10E,14E,16aS)-2,7-Dihydroxy-3-((S)-1-hydroxypropan-2-yl)-6,10,14,16a-tetramethyl-3a,4,8,9,12,13,16,16a-octahydrocyclopenta[15]annulen-1(7H)-one (CAS 146436-22-8), a certified reference material (molecular formula C25H38O4, MW 402.57 g/mol) for analytical method development and quality control.

Based on its molecular formula C25H38O4, (3aR,5E,7S,10E,14E,16aS)-2,7-Dihydroxy-3-((S)-1-hydroxypropan-2-yl)-6,10,14,16a-tetramethyl-3a,4,8,9,12,13,16,16a-octahydrocyclopenta[15]annulen-1(7H)-one contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 402.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
