Application of Chlorosulfonyl Isocyanate CAS 1189-71-5
The chemical properties of the compound are very active. There are chlorosulfonyl groups and isocyanate groups, both of which are very reactive functional groups. Carbon and sulfur atoms are two potentiophile points in the molecule, which can be attacked by nucleophile and carry out a series of addition, substitution, condensation and cyclization reactions. In medicine, it can be used for the synthesis of antibiotic cefuroxime, cefoxitin, pulmonary hypertension treatment drug masititan; Pesticide, can be used for herbicide sulfuron-methyl, bensulfuron-methyl synthesis; In addition, it can also be used in the synthesis of papermaking auxiliaries and the application of lithium battery electrolyte.
