Cas no 19643-45-9 (2,6-Dibromoquinone)

2,6-Dibromoquinone is a brominated quinone derivative characterized by its high reactivity and utility as an intermediate in organic synthesis. The presence of two bromine atoms at the 2 and 6 positions enhances its electrophilic properties, making it valuable for cross-coupling reactions and the preparation of more complex quinone-based compounds. Its well-defined structure and stability under controlled conditions facilitate precise modifications in pharmaceutical, agrochemical, and materials science applications. The compound’s ability to act as a building block for functionalized quinones underscores its importance in research and industrial processes requiring tailored molecular frameworks. Proper handling is advised due to its potential sensitivity to light and moisture.
