Web19 nov. 2024 · Quinoxaline is a low melting solid and is miscible in water. It is a weak base and can form salts with acids. The synthesis of quinoxaline has been extensively studied for the last two decades. A very primitive and effective method to derive quinoxaline is the condensation reaction between ortho phenylenediamine and dicarbonyl compounds [ 2, 3 ].
