What is 2,2-Dimethoxypropane CAS 77-76-9?
2, 2-dimethoxypropane (DMP), as a multifunctional organic intermediate, is widely used in the fields of fine chemicals, medicine and electronics. Its low toxicity and high reactivity support industrial-scale application, but strict precautions must be taken against the risks of flammability, explosiveness and acid sensitivity. The synthesis process is mature, and the domestic market is mainly composed of suppliers from Hubei, Shanghai and other places (such as Canos and Coward).
. When making purchases, it is recommended to give priority to choosing medical-grade certified products (such as USP/NF) to ensure purity.
