Description
This 2-(4-Aminophenyl)benzo[d]oxazol-5-amine features a dual amine-functionalized heteroaromatic scaffold, combining electron-rich phenyl and oxazole moieties. The para-amino substitution enhances conjugation and solubility, enabling efficient integration into bioconjugation workflows and fluorescent probe development under standard conditions.
Application
2-(4-Aminophenyl)benzo[d]oxazol-5-amine serves as a versatile heterocyclic building block for medicinal chemistry and materials science applications. Its dual aniline and oxazole functionalities enable facile coupling reactions, including Suzuki-Miyaura and Ullmann-type transformations. The molecule exhibits good bench stability and facilitates the construction of complex polycyclic scaffolds through directed functionalization at the 5-amino and 4-amino positions.
