4-Chlorophenyl phosphorodichloridate(CAS: 772-79-2)

4-Chlorophenyl phosphorodichloridate is a white crystalline solid with a molecular weight of approximately 274.8 g/mol. It is poorly soluble in water but soluble in organic solvents. It is highly reactive towards nucleophiles and exhibits reactivity towards hydrolysis to form the corresponding acid and phosphoric acid derivatives.

4-Chlorophenyl phosphorodichloridate is typically synthesized by treating 4-chlorophenyl phosphate with hydrochloric acid. The reaction is carried out in a solvent such as methylene chloride or dichloromethane, and the product is isolated by filtration. The yield is usually around 85-90%.

4-Chlorophenyl phosphorodichloridate is used in various industries, including pharmaceuticals for the synthesis of new drugs, and in the production of organic phosphorus compounds. It also finds applications in the synthesis of pesticides, herbicides, and in the preparation of certain polymers and sensors.

Precautions when handling 4-Chlorophenyl phosphorodichloridate include the use of personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up using appropriate absorbent materials and the area should be thoroughly washed. Safety data sheets (SDS) should always be consulted for detailed handling and disposal information.
