Used in the synthesis of pharmaceutical intermediates, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the preparation of active pharmaceutical ingredients (APIs) due to its amine and hydroxyl functional groups, which allow for further chemical modifications. Commonly employed in research settings for designing compounds with biological activity, especially in oncology and inflammatory disease areas. Also utilized in the creation of small molecule drugs where substituted phenylamino ethanol structures are required for target binding.
