Chemical Structure

2',5'-Dichloro-2-fluoro-[1,1'-biphenyl]-4-carboxylic acid CAS 1261954-57-7 chemical structure

Description

The occurrence of 2',5'-Dichloro-2-fluoro-[1,1'-biphenyl]-4-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2',5'-Dichloro-2-fluoro-[1,1'-biphenyl]-4-carboxylic acid (CAS 1261954-57-7), molecular formula C13H7Cl2FO2 and molecular weight 285.10 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2',5'-Dichloro-2-fluoro-[1,1'-biphenyl]-4-carboxylic acid (C13H7Cl2FO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 285.10 g/mol, it falls into the medium-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).
