(±)-Propylene oxide, >99%, Thermo Scientific Chemicals

Description

CAS: 75-56-9 | C3H6O | 58.08 g/mol

Propylene oxide is used as a precursor in the production of polyether polyols, which is utilized for making polyurethane plastics, polypropylene glycols, propylene glycol ethers and propylene carbonate. It is involved in the preparation of biological samples for electron microscopy. It plays a vital role in the removal of residual ethanol previously used for dehydration. Further, it is used in thermobaric weapons, and microbial fumigation. It is also used as solvents, and in the preparation of surfactants, lubricants and in oil demulsifiers.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
