Abstract

Methylene bis anthranilic acid was synthesized by reacting anthranilic acid with formaldehyde in water at room temperature. The resulting compound was further treated with nitrous acid to form tetrazonium salts, which were then coupled with phenol and 2-naphthol to produce disazo derivatives. The structures of the synthesized compounds were confirmed using spectral analysis (e.g., IR, NMR), and the desired products were successfully obtained.
