N-Chlorosuccinimide (Cat No.: R019776) is a chlorinating and oxidizing agent widely used in organic synthesis. It is a white crystalline compound derived from succinimide, with a chlorine atom bonded to the nitrogen atom. NCS is commonly used for selective chlorination of alkenes, aromatics, and activated methylene groups, offering milder reaction conditions compared to elemental chlorine. It also serves as a reagent in halogenation and oxidation reactions in pharmaceuticals and fine chemical production. NCS is valued for its stability, ease of handling, and controlled reactivity.
