Benzenesulfonyl chloride is prepared by reaction of benzene and chlorosulfonic acid or from the sodium salt of benzenesulfonic acid and PCl5 or POCl3. It reacts with Grignard reagent from N-unsubstituted indoles to form oxindoles or substituted indoles. Benzenesulfonyl chloride is the derivatization reagent for the determination of various amines in waste water and surface water at the sub-ppb level by gas chromatography-mass spectrometry.
Benzine 2,5 L is primarily used as a solvent to dissolve various organic compounds like fats, resins, and waxes due to its excellent solvency properties; it's also employed as a reagent in chemical reactions, particularly in organic synthesis, because of its reactivity and stability.
