Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (20R)-13(17)-Diacholestene.
(20R)-13(17)-Diacholestene (CAS 82079-08-1) is a high-purity analytical reference standard with the molecular formula C27H46 and a molecular weight of 370.65 g/mol.
Based on its molecular formula C27H46, (20R)-13(17)-Diacholestene contains an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 370.65 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.
