13-(3,4-Dichlorophenyl)-11,12-dimethyl-4,6,10-trioxatricyclo[7.4.0.0^{3,7}]trideca-1(9),2,7-trien-11-ol (CAS 1005188-49-7) is a high-purity analytical reference standard with the molecular formula C18H16Cl2O4 and a molecular weight of 367.22 g/mol.
Structurally, 13-(3,4-Dichlorophenyl)-11,12-dimethyl-4,6,10-trioxatricyclo[7.4.0.0^{3,7}]trideca-1(9),2,7-trien-11-ol (C18H16Cl2O4) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 367.22 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.
