Brief Introduction

4-dimethylaminobenzoic acid is an organic intermediate, which can be methylated from ethyl p-aminobenzoate to ethyl 4-dimethylaminobenzoate, and then hydrolyzed to ethyl 4-dimethylaminobenzoate; Or it is obtained by coupling p-chlorobenzoic acid with dimethylamine. It is used in intermediates of fine chemicals, synthesis of high-efficiency photosensitive materials, photoelectric conversion devices, coatings and UV radiation. As an important intermediate of photosensitizer, coating and dye intermediate.
