(±)-Propylene oxide
(±)-Propylene oxide (CAS: 75-56-9; C3H6O) is a colourless, volatile liquid with a sweetish odour. It is a highly reactive epoxide used primarily as a chemical intermediate in the synthesis of various organic compounds. Its high reactivity makes it a valuable building block for polymers, polyols, and surfactants. This highly flammable liquid requires careful handling due to its hazardous nature, and is available in SAJ special grade.

Polyether Polyols Production
Serves as a key monomer in the production of polyether polyols, essential components for polyurethanes used in foams, coatings, and elastomers.
Surfactant Synthesis
Reacts with alcohols to form propylene glycol ethers, which are widely used as solvents and surfactants in detergents, cleaners, and coatings.
Organic Synthesis Intermediate
Acts as a versatile building block in organic chemistry for introducing the hydroxypropyl group into molecules, facilitating the synthesis of pharmaceuticals and fine chemicals.
Propylene Glycol Production
Used in the synthesis of propylene glycol, a compound with applications in antifreeze, de-icing fluids, and as a solvent in food and pharmaceutical industries.
