CS powder is a kind of chemical weapon, its scientific name is o-chlorobenzylidene malononitrile, and its chemical formula is C10H5ClN2. It is a non-lethal tear gas widely used by police all over the world. O-Chlorobenzylidene malononitrile itself is a solid at room temperature. Generally, the poison gas used for spraying is an aerosol formed by mixing the substance and a volatile solvent. When humans are exposed to CS powder tear gas, they will be affected by the burning sensation of the respiratory tract, leading to tearing, difficulty breathing, runny nose, coughing, loss of consciousness, and loss of resistance.
CS was first synthesized by two Americans, Ben Corson and Roger Stoughton, at Mingde University in 1928. The name CS is derived from the initials of these two surnames. In the 1950s and 1960s, CS gas powder became the subject of secret weapon research and development experiments in Porton Down, Wiltshire, England. The experiment was first carried out on animals and then transferred to British Army personnel for testing. The CS powder has a poor effect on animals, which is related to the animal's "lacrimal gland degeneration and fur covering".
CS powder is also called 2 chlorobenzalmalononitrile. The tear gas powder is white flake crystals with a boiling point of 310～315℃. The melting point is 93～95℃, and the volatility is very small. The CS powder has a peppery taste, is hardly soluble in water, slightly soluble in alcohol, and easily soluble in organic solvents such as benzene, chloroform, acetone, etc. It is not easy to be hydrolyzed. Heating or adding alkali can accelerate the hydrolysis. Although it can be oxidized by oxidants such as potassium permanganate and hypochlorite such as chlorine bleach, the chemical reaction will be quite violent, and more toxic compounds will be produced.
DAYU Chemical has high quality CS powder for sale. And we also sell capsaicin powder bulk which is another type of tear gas.
Various types of CS powder gas cartridges collected during the Turkish anti-government protest movement in 2013. In Western countries, the CS stimulant has not only become a powerful weapon for the military and police to suppress violence and maintain law and order, but it has also become a self-defense item for civilians. Like pepper spray, CS powder spray is one of the standard police equipment used by law enforcement officers in some countries. The CS is not only loaded into hand grenades, bullets and hand sprayers, but also loaded into the vehicle-mounted chemical sprayer for mobile riot suppression tasks. CS is also packed into containers of various shapes, such as perfume bottles, for women and other users to use in self-defense.
