N,N'-Diisopropylcarbodiimide is mainly used as a dehydrating agent for bumicanamycin, glutathione, and can also be used for the synthesis of anhydride, aldehydes, ketones and isocyanates; N,N'-diisopropylcarbodiimide as a dehydration condensation agent, can be formed at room temperature by a short reaction, and the product after the reaction is dichemicalbook isopropylurea. It can also be used for the synthesis of peptides and nucleic acids, and it can be easily synthesized from compounds with free carboxyl groups and free amino groups at room temperature. N,N'-Diisopropylcarbodiimide is widely used in medicine, health care products, cosmetics, biological agents and other organic synthesis fields.
