Informazioni sul prodotto
- Quinazoline, 4-Chloro-6,7-Difluoro-
4-Chloro-6,7-difluoroquinazoline is an impurity that is produced during the amidation reaction of chlorination. The triethylene glycol is a reagent that can be used as a solvent system in high temperature reactions. Amidation of chlorination and icotinib is a condensation reaction that produces the triethylene glycol. The alkali reacts with the cyclization reaction to produce 4-chloro-6,7-difluoroquinazoline, which is then chlorinated.
