4-Hydroxyindoline is an organic compound characterized by its indoline structure, which consists of a fused benzene and pyrrole ring with a hydroxyl group (-OH) attached to the carbon at the 4-position of the indoline moiety. This compound typically appears as a solid at room temperature and is known for its potential applications in organic synthesis and as an intermediate in the production of dyes and pharmaceuticals. The presence of the hydroxyl group contributes to its reactivity, allowing for various chemical transformations, such as oxidation and substitution reactions. 4-Hydroxyindoline is also of interest in the field of materials science, particularly in the development of organic semiconductors and light-emitting devices. Its solubility can vary depending on the solvent, and it may exhibit distinct spectral properties, making it useful for analytical applications. As with many organic compounds, safety precautions should be observed when handling 4-Hydroxyindoline, as it may pose health risks if ingested or inhaled.

4-Hydroxyindoline is a synthetic compound that is used as a dehydrative coupler in the synthesis of polymers. It can be produced by refluxing indoline with paraformaldehyde and an acidic ph. This process can also be conducted using human keratin, which yields a more pure product. 4-Hydroxyindoline is used in the production of polyurethane, polyester, and vinyl resins. It reacts with alcohols to produce reactive groups that are important for polymerization reactions. These groups include hydroxyl, carbonyl, and amino groups. The most common use of 4-hydroxyindoline is as a reactive dye in keratin fibers to produce staining effects.
