Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 260.29 g/mol gives 1,2-Dihydroxychrysene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,2-Dihydroxychrysene (CAS 138142-87-7) is a high-purity analytical reference standard with the molecular formula C18H12O2 and a molecular weight of 260.29 g/mol.
Structurally, 1,2-Dihydroxychrysene (C18H12O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 260.29 g/mol, it falls into the medium-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.
CATO manufactures 1,2-Dihydroxychrysene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
