The occurrence of 19-Hydroxy Androstendione-19-d2 19-Hydroxyandrost-4-ene-3,17-dione-19,19-d2 71995-64-7 Androst-4-en-19-ol-3,17-dione-d2 Androst-4-ene-3,17-dione-19-ol-d2 NSC 74233-d2 is closely related to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
19-Hydroxy Androstendione-19-d2 19-Hydroxyandrost-4-ene-3,17-dione-19,19-d2 71995-64-7 Androst-4-en-19-ol-3,17-dione-d2 Androst-4-ene-3,17-dione-19-ol-d2 NSC 74233-d2 (CAS 71995-64-7) is a high-purity analytical reference standard with the molecular formula C19H24D2O3 and a molecular weight of 304.42 g/mol.
Structurally, 19-Hydroxy Androstendione-19-d2 19-Hydroxyandrost-4-ene-3,17-dione-19,19-d2 71995-64-7 Androst-4-en-19-ol-3,17-dione-d2 Androst-4-ene-3,17-dione-19-ol-d2 NSC 74233-d2 (C19H24D2O3) contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 304.42 g/mol, it falls into the moderately-high-molecular-weight range. 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.
