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 17β-Hydroxy-17α-methyl-5α-estran-3-one.
17β-Hydroxy-17α-methyl-5α-estran-3-one (CAS 6424-04-0), molecular formula C19H30O2 and molecular weight 290.44 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H30O2, 17β-Hydroxy-17α-methyl-5α-estran-3-one 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 290.44 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.
