3-Hydroxyindole(CAS: 480-93-3)

3-Hydroxyindole is a crystalline solid with a molecular weight of approximately 138.15 g/mol. It has a melting point of 270-272°C and is slightly soluble in water. Chemically, it is less reactive compared to other indoles, showing moderate basicity and limited reactivity under neutral conditions. Its low solubility and stability make it valuable for various applications in organic synthesis and chemical research.

3-Hydroxyindole can be synthesized via various methods, including the reduction of indole-3-carboxaldehyde with hydrogen in the presence of a palladium catalyst or through the reaction of indole-3-carboxylic acid with a reducing agent like sodium borohydride. These processes yield high selectivity and moderate to good yields, making them suitable for laboratory and industrial-scale production.

3-Hydroxyindole is primarily used in the pharmaceutical industry for the synthesis of bioactive compounds and in the production of certain medicinal agents. It also finds applications in the polymer industry for developing specialized materials, and in sensor technology for its ability to interact with specific molecules. Additionally, it is used in the semiconductor industry for various analytical and research purposes.

When handling 3-Hydroxyindole, it is important to use appropriate personal protective equipment (PPE), such as gloves, goggles, and a lab coat. Handling should be done in a well-ventilated area or under a fume hood to minimize inhalation risks. Spills should be cleaned up using appropriate spill kits, and the material safety data sheet (MSDS) should be consulted for detailed safety information and emergency procedures. Storage should be in a cool, dry place away from direct sunlight and flammable materials.
