Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the production of beta-adrenergic blockers and other cardiovascular drugs. Its structure allows for selective modifications, making it valuable in developing active pharmaceutical ingredients. It is also employed in research settings for the preparation of chiral molecules through asymmetric synthesis. Due to its reactivity, it plays a role in forming carbon-carbon bonds during multi-step organic syntheses. Handling requires caution due to potential irritant properties.
