Description

5-Nitro-o-toluenesulfonic acid is a sulfonating agent that reacts with amines to form 5-nitroso derivatives. This reaction can be used for the determination of amines in water samples, such as wastewater and river water. The analytical method is based on the detection of nitrosamines by gas chromatography with electron capture detection (GC/ECD). 5-Nitro-o-toluenesulfonic acid reacts with amines to form 5-nitroso derivatives that are characterized by their increased solubility in hydrochloric acid and their decreased solubility in hydroxide solution. The reaction mechanism has been determined using solubility data and activation energies. Photochemical properties are also studied to determine the reactivity of this compound. It is found that this compound could be used as a receptor for some drugs, but not others.
