Potassium dibenzyl phosphate（CAS#78543-37-0）
Potassium dibenzyl phosphate（CAS#78543-37-0）
Physicochemical properties
Appearance: Mostly as a solid, usually granular or powdery. This form is convenient for metering during storage, transportation and use.
Boiling Point: At 101.3kPa, the boiling point is about 300°C. This data indicates that it does not vaporize until it occurs at relatively high temperatures, and is stable over the typical laboratory and industrial operating temperature range.
Vapor pressure: At 85 - 115°C, the vapor pressure is about 0.001Pa. The lower vapor pressure means that less volatilization is released into the air during this temperature range, reducing losses due to volatilization and potential environmental impact.
Fields of application
Organic synthesis: As an organophosphorus reagent, it can participate in a variety of organic synthesis reactions and is used to construct complex organic molecular structures containing phosphorus atoms. For example, in some specific reactions, the activity of its phosphorus atom can react with other organic reagents such as nucleophilic substitution and addition, which provides a way for the synthesis of organophosphorus compounds with special functions, and these compounds may have unique application value in medicine, materials and other fields.
Materials science research: In the field of materials science, it may be used as an additive or modifier in the preparation of certain materials. By introducing it into the material system, using its molecular structure and chemical properties, changing some properties of the material, such as improving the flame retardancy of the material, improving the mechanical properties of the material or giving the material special optical and electrical properties, although there are relatively few relevant application reports, with the deepening of research, it is expected to play a role in the development of new materials.
Application
Potassium dibenzyl phosphate (CAS 78543-37-0) is a versatile organophosphate salt that functions as a phosphorylating agent, chemical intermediate, and flame retardant additive. In pharmaceutical research, it serves as a key building block for introducing dibenzyl phosphate groups into target molecules via nucleophilic substitution or metal-catalyzed cross-coupling reactions. Its potassium cation enhances solubility in polar organic solvents compared to other counterions. The compound is also reported to exhibit antiviral activity by inhibiting protease enzymes, with demonstrated effectiveness against hepatitis B virus. In polymer science, potassium dibenzyl phosphate is incorporated into plastics, coatings, and adhesives as a flame retardant, stabilizer for PVC products, and lubricant additive, improving thermal stability and fire resistance. The benzyl groups serve as protecting groups that can be selectively removed by hydrogenolysis, enabling sophisticated synthetic strategies for complex phosphate derivatives.
