Brief Introduction

Perfluoroalkane is a kind of intermediate, and its toxicity is significantly lower than that of perfluoroalkyl iodide. Among them, c8f17br and c10f21br are the main raw materials for preparing the second generation of human hematopoiesis. Perfluorooctane can be obtained by one-step reaction of liquid bromine and perfluorooctane.
