Application
2-(5-Amino-2-hydroxyphenyl)benzothiazole is a fluorescent dye that may be used in the synthesis of a photoactive hybrid material by dispersion in a silica matrix with potential application in optical sensors. It may also be used to synthesize N-[3-(benzothiazol-2-yl)-4-hydroxyphenyl]-octanamide that shows the existence of an excited-state intramolecular proton transfer (ESIPT) process.
