Used as an intermediate in organic synthesis, particularly in the production of dyes, pharmaceuticals, and agrochemicals. Acts as a corrosion inhibitor in metalworking fluids and helps in the extraction of metals during hydrometallurgical processes. Also serves as a flotation agent in mineral processing to separate valuable ores from gangue materials. Its solvency and basicity make it useful in catalytic reactions and as a component in surfactants and emulsifiers.
