| properties | 4-Chlorostyrene, also known as 4-Chlorostyrene, has a molecular formula of C8H7Cl, a molecular weight of 138.59, a CAS number of 1073-67-2, a boiling point of 192 oC, a density of 1.155g/cm3, and a colorless or light yellow liquid. Since the side chain is a C = C double bond, the chemical properties are more active. The compound can be slowly polymerized at room temperature, and a polymerization inhibitor (stabilizer) must be added to store it. |
| application | p-chlorophenylethene is a very important chemical raw material, and its derivatives can be applied to ion exchange resins, functional polymers, photosensitive polymers, polymer catalysts, medicines, pesticides, etc. It can also be made into Grignard reagent to synthesize polymerizable photoinitiators, which has broad market prospects. |
