Chemical Structure
Description
The occurrence of 25279-15-6 Dammaran-3-one, 20,24-epoxy-12,25-dihydroxy-, (12beta,24R)- is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
25279-15-6 Dammaran-3-one, 20,24-epoxy-12,25-dihydroxy-, (12beta,24R)- (CAS 25279-15-6), molecular formula C30H50O4 and molecular weight 474.72 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C30H50O4, 25279-15-6 Dammaran-3-one, 20,24-epoxy-12,25-dihydroxy-, (12beta,24R)- contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 474.72 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.
