Chemical Structure

(R)-3,3'-Bis(4-methylphenyl)-1,1'-bi-2-naphthol CAS 1242419-39-1 chemical structure

Description

Structurally, (R)-3,3'-Bis(4-methylphenyl)-1,1'-bi-2-naphthol (C34H26O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 22.0, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 466.57 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.
