.Malachite Green Oxalate presents itself as a deep green crystalline solid. This synthetic dye compound bears the chemical formula C23H25N2€š¬¢C2HO4€š¬¢0.5C2H2O4 and is also recognized as N,N,N?,N?-Tetramethyl-4,4?-diaminotriphenylcarbenium oxalate, or Basic Green 4. Unlike Malachite Green Hydrochloride, it shares a similar structure but features oxalate as the counterion instead of chloride. Belonging to the triphenylmethane dye family, it showcases a central carbon atom linked to three phenyl rings and a dimethylamino group. The oxalate ion (C?H?O?) serves as the counterion, leading to the formation of the oxalate salt. Notably, Malachite Green Oxalate boasts a unique green hue and demonstrates solubility in water, alcohol, and various organic solvents.
