CAS 75-56-9

(±)-Propylene oxide

Description:

(±)-Propylene oxide, with the CAS number 75-56-9, is a colorless, flammable liquid with a characteristic odor. It is an epoxide, a three-membered cyclic ether, which makes it highly reactive, particularly with nucleophiles. This compound is used primarily as an intermediate in the production of polyether polyols for polyurethane foams, as well as in the synthesis of various chemicals. Its molecular formula is C3H6O, and it has a relatively low boiling point, which contributes to its volatility. The compound exhibits both polar and nonpolar characteristics due to the presence of the ether oxygen, allowing it to dissolve in a variety of solvents. Additionally, (±)-propylene oxide is known for its potential health hazards, including irritation to the skin, eyes, and respiratory system, and it is classified as a possible human carcinogen. Proper handling and safety precautions are essential when working with this substance in industrial and laboratory settings.
