(1R)-2-Amino-1-[4-(methylsulfonyl)phenyl]ethanol is primarily used in the pharmaceutical industry as an intermediate in the synthesis of various active pharmaceutical ingredients (APIs). Its structure, featuring both an amino group and a sulfonyl group, makes it a valuable building block for the development of drugs targeting specific biological pathways.

One of its key applications is in the production of beta-blockers, which are medications used to manage cardiovascular conditions such as hypertension, arrhythmias, and heart failure. The compound's chiral center allows for the creation of enantiomerically pure drugs, enhancing their efficacy and reducing potential side effects.

Additionally, it is utilized in the synthesis of compounds with anti-inflammatory and analgesic properties, making it relevant in the development of treatments for chronic pain and inflammatory disorders. Its versatility in organic synthesis also extends to research applications, where it serves as a precursor for novel therapeutic agents in drug discovery programs.
