3',5'-Dichloro-[1,1'-biphenyl]-3-sulfonylchloride CAS 885950-92-5

Description

Compared with other compounds in its class, the molecular weight of 321.61 g/mol gives 3',5'-Dichloro-[1,1'-biphenyl]-3-sulfonylchloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3',5'-Dichloro-[1,1'-biphenyl]-3-sulfonylchloride (CAS 885950-92-5) is a high-purity analytical reference standard with the molecular formula C12H7Cl3O2S and a molecular weight of 321.61 g/mol.

Structurally, 3',5'-Dichloro-[1,1'-biphenyl]-3-sulfonylchloride (C12H7Cl3O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 321.61 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.

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.
