Chemical Structure
Description
The occurrence of 3-Nitro-4-(trifluoromethoxy)benzenesulfonyl chloride is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Nitro-4-(trifluoromethoxy)benzenesulfonyl chloride (CAS 1351094-07-9) is a high-purity analytical reference standard with the molecular formula C7H3ClF3NO5S and a molecular weight of 305.62 g/mol.
Structurally, 3-Nitro-4-(trifluoromethoxy)benzenesulfonyl chloride (C7H3ClF3NO5S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 305.62 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).
