Chemical Structure

4,4'-(Anthracene-9,10-diyl)dibenzoic acid CAS 42824-53-3 chemical structure

Description

The occurrence of 4,4'-(Anthracene-9,10-diyl)dibenzoic acid is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,4'-(Anthracene-9,10-diyl)dibenzoic acid (CAS 42824-53-3) is a high-purity analytical reference standard with the molecular formula C28H18O4 and a molecular weight of 418.44 g/mol.

Structurally, 4,4'-(Anthracene-9,10-diyl)dibenzoic acid (C28H18O4) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 418.44 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
