Chemical Structure
Description
The occurrence of [1,1'-Biphenyl]-4-yltrichlorosilane is closely related to chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
[1,1'-Biphenyl]-4-yltrichlorosilane (CAS 18030-61-0) is a high-purity analytical reference standard with the molecular formula C12H9Cl3Si and a molecular weight of 287.64 g/mol.
Structurally, [1,1'-Biphenyl]-4-yltrichlorosilane (C12H9Cl3Si) contains chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 287.64 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).
