Chemical Structure
Description
Structurally, 1,2-Dichloro-4-(isocyano(tosyl)methyl)benzene (C15H11Cl2NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 340.22 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).
1,2-Dichloro-4-(isocyano(tosyl)methyl)benzene (CAS 263389-52-2), molecular formula C15H11Cl2NO2S and molecular weight 340.22 g/mol, is a CATO reference standard with documented purity and traceability.
