Benzyl Chloride (CAS#100-44-7)
Benzyl chloride is an organic halogenated hydrocarbon that is flammable, toxic, and corrosive. It appears as a colorless to pale yellow transparent liquid with a strong pungent odor. Owing to the presence of active benzyl groups in its molecular structure, it exhibits high chemical reactivity.
It is insoluble in water but miscible with most organic solvents, including ethanol, ether, benzene, and dichloromethane. In addition, it has strong dissolving ability for organic substances such as oils and resins, and can also be used as a solvent in certain industrial applications.

Product Usage
Benzyl chloride is primarily used as a pharmaceutical intermediate, as well as a key raw material in the dye, pigment, fragrance, and daily chemical industries. It is also widely applied in the plastics and rubber sectors for the synthesis of PVC stabilizers and rubber vulcanization accelerators. In the pesticide industry, it serves as an important intermediate for producing insecticides and herbicides. Additionally, it is used in limited quantities as an organic synthesis solvent and as a raw material for electronic chemicals.
