Product Name:phosphinylidynetrimethanol
English Name:phosphinylidynetrimethanol
CAS No.:1067-12-5
Aliases:Tris(hydroxymethyl)phosphine oxide
Molecular Formula:C3H9O4P
Physical Properties:White crystalline solid. Density: 1.478±0.06 g/cm³ (predicted); melting point: 56-58 °C; boiling point: 504.9±45.0 °C (predicted). Solubility: 1000 g/L in water at 25 °C; vapor pressure: 0.001 Pa at 25 °C; pKa: 12.26±0.10 (predicted).
Uses:Tris(hydroxymethyl)phosphine oxide (THPO) is a multifunctional organophosphorus compound with high phosphorus content, free of halogens, and exhibiting excellent thermal stability and hydrolysis resistance. It is commonly used as an environmentally friendly flame retardant in rigid polyurethane foam insulation boards, adhesives, and other polymer materials. In organic synthesis, it serves as a reactive curing agent, organic catalyst, and hydroxyl protecting group. It is also applied as an advanced lubricant additive and a starter for producing flame-retardant polyether polyols, widely used in chemical, plastics, and lubricant manufacturing industries.
Technical Specifications:
