Application
N,N'-Dimethylpropylneurea(DMPU) is a multifunctional non proton polar solvent widely used in the fields of organic synthesis and material preparation. The following are its main applications:
1.N,N'-Dimethylpropylneurea can promote the reaction of primary amines with alkylating agents to generate chiral compounds.
2.N,N'-Dimethylpropylneurea acts as a solvent or catalyst to accelerate the conversion of aldose and alkylating reagents.
3.N,N'-Dimethylpropylneurea is used as a reaction medium to participate in the preparation of aromatic ether polymers.
4.Alternative HMPA: In nucleophilic reagents and alkaline co solvents, N,N'-Dimethylpropylneurea can reduce the risk of toxicity.
5.High boiling point solvent: N,N'-Dimethylpropylneurea is convenient and stable to operate in filtration, distillation and other processes due to its low melting point and high boiling point characteristics.
Storage
Store in a cool, dry, dark, ventilated place. Avoid contact with strong oxidants, strong acids and bases to prevent chemical reactions.
