Definitions
- the present invention relates to a high-purity 2-cyanophenolic acid or ester thereof, which can be a raw material for pharmaceuticals and electronic materials, and a method for producing the same.
- 2-Cyanophenylboronic acid and its derivatives are useful as raw materials for electronic materials such as pharmaceuticals and liquid crystals used in the Suzuki coupling reaction.
