Chemical Structure
Description
The occurrence of Potassium 4-chloro-3,5-dinitrobenzenesulfonate is closely related to a salt form, a carbohydrate-derived structure, an amide group, a sulfone group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Potassium 4-chloro-3,5-dinitrobenzenesulfonate (CAS 38185-06-7) is a high-purity analytical reference standard with the molecular formula C6H2ClN2O7SK and a molecular weight of 320.70 g/mol.
Owing to a salt form, a carbohydrate-derived structure, an amide group, a sulfone group, chlorine substitution, Potassium 4-chloro-3,5-dinitrobenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
