Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8 β,9α-Dihydroxy-10 β,11 β-epoxy-8,9,10,11-tetrahydrobenzo[a]anthracene.
8 β,9α-Dihydroxy-10 β,11 β-epoxy-8,9,10,11-tetrahydrobenzo[a]anthracene (CAS 64937-39-9) is a high-purity analytical reference standard with the molecular formula C18H14O3 and a molecular weight of 278.30 g/mol.
8 β,9α-Dihydroxy-10 β,11 β-epoxy-8,9,10,11-tetrahydrobenzo[a]anthracene (C18H14O3) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
