Applications of 4712-55-4
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Co-heat stabilizer for polyvinyl chloride (PVC) and vinyl chloride copolymers | Used in ester exchange or direct compounding with primary stabilizers (e.g., Ca/Zn or Ba/Zn stabilizers) to scavenge hydrogen chloride released during degradation and inhibit long-term thermal aging |
| Plastics Industry | Synthetic intermediate for antioxidants and light stabilizers (e.g., antioxidants, UV absorbers) | Serves as an organic synthetic intermediate, incorporated into polymer structures via polymerization or modification reactions, or added directly to polymer systems |
| Agrochemical Industry | Synthetic intermediate for organophosphorus pesticides and insecticides | Employed in Arbuzov or Michael addition reactions to construct P–C or P–O–C bonds |
| Pharmaceutical Industry | Synthetic intermediate for drug synthesis (e.g., construction of phosphorus-containing drug molecules or as a phosphorylation reagent) | Utilized in drug molecule modification or synthesis pathways to introduce phosphite functional groups via its phosphylating properties |
| Rubber Industry | Antidegradant or auxiliary additive for synthetic rubber | Participates in the chemical synthesis of rubber additives to enhance the heat resistance and aging resistance of rubber products |
