5-Chloro-4-hydroxy-[1,1'-biphenyl]-3-carbaldehyde CAS 1248288-65-4

Description

The occurrence of 5-Chloro-4-hydroxy-[1,1'-biphenyl]-3-carbaldehyde is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Chloro-4-hydroxy-[1,1'-biphenyl]-3-carbaldehyde (CAS 1248288-65-4) is a high-purity analytical reference standard with the molecular formula C13H9ClO2 and a molecular weight of 232.66 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 5-Chloro-4-hydroxy-[1,1'-biphenyl]-3-carbaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
