FAQ

What is Trimethyl phosphate (CAS: 512-56-1)?

Trimethyl phosphate (CAS: 512-56-1) is a colorless, water-soluble liquid with the chemical formula (CH3)3PO. It is commonly used as a precursor in organic synthesis and exhibits low reactivity under normal conditions. Known for its stability and versatility, it serves as a key intermediate in various chemical processes.

What are the main uses of Trimethyl phosphate (CAS: 512-56-1)?

Trimethyl phosphate (CAS: 512-56-1) is widely utilized in pharmaceuticals for drug synthesis, in industrial applications as a flame retardant and plasticizer, in the food industry as an emulsifier, and in research for producing catalysts and chemical intermediates. Its utility stems from its ability to modify polymer properties and act as a phosphate ester.

Is Trimethyl phosphate (CAS: 512-56-1) safe?

Trimethyl phosphate (CAS: 512-56-1) is generally considered safe in low concentrations, but proper handling is essential. It may cause skin and eye irritation, so protective measures like gloves and goggles are recommended. Safety standards emphasize avoiding inhalation of vapors and following OSHA guidelines for storage and disposal.

How should Trimethyl phosphate (CAS: 512-56-1) be stored?

Trimethyl phosphate (CAS: 512-56-1) should be stored in a sealed, airtight container in a cool, dry place, away from light and heat sources. Maintain storage at temperatures below 25°C and ensure humidity levels are controlled to prevent degradation. Keep it in well-ventilated areas and follow chemical storage regulations for safety.
