Quinolin-2-ol is widely used in the pharmaceutical industry as a key intermediate in the synthesis of various drugs, particularly those with antimicrobial and anti-inflammatory properties. It serves as a building block for creating compounds that target bacterial and fungal infections. Additionally, it is utilized in the development of antimalarial medications due to its structural similarity to quinine derivatives. In organic chemistry, it acts as a ligand in catalytic processes, facilitating complex reactions. Its derivatives are also explored in material science for their potential in creating fluorescent dyes and sensors. Furthermore, Quinolin-2-ol is studied for its role in agrochemicals, contributing to the development of pesticides and herbicides.
