  Description:
  O-bromocinnamic acid (C9H7BrO2) is a white crystal with a melting point of 215 °C. Insoluble in water, soluble in ethanol and hot oil. It is a very dangerous pharmaceutical intermediate that is irritating to the eyes, respiratory tract and skin. But O-bromocinnamic acid is a very potent pharmaceutical intermediate, mainly used in the manufacture of pesticides, chemicals, hormones,and fertilizeretc. When you refine or use the medicine synthesized by it, if it comes into contact with your eyes, immediately rinse it with plenty of water and send it to the doctor. Always wear appropriate protective clothing, gloves, and protective goggles or a face shield.
