Chemical Structure
Description
The occurrence of 2,3',4,4',5-Pentachloro[13C12]biphenyl is closely related to chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,3',4,4',5-Pentachloro[13C12]biphenyl (CAS 104130-40-7) is a high-purity analytical reference standard with the molecular formula C12H5Cl5 [13C]6H2 C4[13C]2H2 and a molecular weight of 402.52 g/mol.
Structurally, 2,3',4,4',5-Pentachloro[13C12]biphenyl (C12H5Cl5 [13C]6H2 C4[13C]2H2) contains chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 402.52 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).
