2-[(4,7-Dimethyl-2-benzothiazolyl)amino]ethanol, with CAS number 775351-65-0, is an organic compound featuring a benzothiazole core substituted with methyl groups at the 4 and 7 positions and an ethanolamine side chain attached via an amino linkage at the 2-position. This structure combines an electron-deficient benzothiazole heterocycle with a flexible, polar ethanol moiety. This compound is primarily utilized as a key intermediate or building block in the synthesis of organic light-emitting diode (OLED) materials and other organic electronic components. The benzothiazole unit is a classic electron-accepting (n-type) moiety in organic semiconductors, and functionalization with the aminoethanol group allows for further chemical modifications to create more complex molecular architectures, such as host materials, emitters, or charge-transporting materials for OLED devices. Its role is foundational in materials chemistry research focused on developing new optoelectronic properties. While not a final device material itself, it serves as a crucial synthetic precursor, placing it firmly within the domain of OLED material precursors. Its well-defined structure also makes it a specific example of an amine-containing organic synthesis building block.
