Characteristic:

It is white crystal powder, dissoluble in water, ethanol, and ethyl ether; slightly dissolve in acetone, but does not dissolve in fatty hydrocarbon and trichlene.

Usage:

It mainly used for synthesizing halogenated hydantoin and DMDM hydantoin, and it also can be used for compounding hydantoin epoxy resin and hydantoin formaldehyde resign. Under catalysis and heat, it hydrolyzes to dimethylglycine. It can be made to insects killing chemical when synthesizing with metal-organic compound.
