5-Aminoindan is primarily used in the synthesis of various pharmaceutical compounds. It serves as a key intermediate in the production of drugs that target neurological disorders, such as Parkinson's disease and depression. Its structure is particularly valuable in the development of monoamine oxidase inhibitors (MAOIs), which are used to treat these conditions. Additionally, it is utilized in the creation of indane derivatives, which have potential applications in anti-inflammatory and analgesic medications. Researchers also explore its use in organic synthesis to develop novel compounds with potential therapeutic effects. Its role in medicinal chemistry highlights its importance in advancing treatments for complex diseases.
