Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Trans-Diethyl-1,1,1’,1’-Stilbestrol-3,3’,5,5’-D8.
CATO supplies Trans-Diethyl-1,1,1’,1’-Stilbestrol-3,3’,5,5’-D8 (CAS 91318-10-4), a certified reference material (molecular formula C18H12D8O2, MW 276.40 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H12D8O2, Trans-Diethyl-1,1,1’,1’-Stilbestrol-3,3’,5,5’-D8 contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 276.40 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.
