Used primarily as an intermediate in organic synthesis, especially in the preparation of dyes and pharmaceuticals. It plays a key role in coupling reactions where carboxylic acid derivatives are involved, enabling the formation of amide or ester bonds under controlled conditions. Its structure allows for selective reactivity, making it valuable in the development of complex molecules in medicinal chemistry. Also utilized in research settings for modifying bioactive compounds due to its ability to introduce dimethylaminobenzoyl groups.
