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.
