CAS:2240-41-7 | Dimethyl Phenylphosphonate

Properties:

Dimethyl Phenylphosphonate, CAS No. 2240-41-7, is an important organophosphorus compound with a molecular formula of C₈H₁₁O₃P and a molecular weight of 186.14 g/mol. Its molecular structure contains a benzene ring and a dimethyl phosphonate group, presenting a colorless to light yellow transparent liquid state with a faint aromatic odor.
Dimethyl Phenylphosphonate is insoluble in water, but is miscible with organic solvents such as ethanol, ether, and acetone. It has a density of 1.19 g/cm³ (20°C), a boiling point of 247°C, a flash point of 154°C, a refractive index of 1.508–1.510, and is stable at high temperatures.

USES:

Pharmaceutical intermediates: Dimethyl Phenylphosphonate is used to synthesize antiviral drugs, cardiovascular drugs and antibiotic precursors, for example, by introducing phosphoryl structures through nucleophilic substitution reactions to enhance the biological activity of drugs.
Flame retardants: As an additive flame retardant, it has a high phosphorus content and can effectively improve the flame retardant properties of plastics, rubbers and coatings, especially for materials such as polyurethane and epoxy resins.
Organic synthesis reagents: As a phosphating agent, it participates in the synthesis of phosphate compounds, for example, for the preparation of surfactants, pesticide synergists and functional materials.
Electronic chemicals: Used as a photoresist additive in semiconductor manufacturing to improve the thermal stability and resolution of photoresists.
