Usage

Uses

Used in Pharmaceutical Industry:
NSC64342 is used as a reactant/reagent for the preparation of 7H-pyrrolo[2,3-d]pyrimidine and 1H-pyrrolo[3,2-c]pyridine derivatives, which are herbicidal compounds. These derivatives have potential applications in the development of new herbicides to control the growth of unwanted plants and improve crop yields.
