Molecular formula :
nature : also known as Pin Lu, block Green, Green. Green is the crystallization of a metallic sheen, easily soluble in water and aqueous solution was blue and green; Soluble ethanol, methanol, amyl alcohol. The existence of hydrochloric acid or sulfuric acid, formaldehyde and benzene 1mol 2molN, N-dimethylaniline condensation, then used lead oxide oxidation product of their goods that at the present; Or the goods may also be N, N-dimethylaniline with α, α, α - Benzotrichloride in heating system. For colorings; Determination of sulfite, cerium, tungsten reagents; PH indicator [0.0 (yellow) to 2.0 (Green); 11.0 (Green) ~ 13.5 (colorless)]. There are still commonly used oxalate, said solid green (fast Green), the chemical formula (C23H25N2) 2C2O4 2H2C2O4 k, with a metallic sheen to the green flake crystals, is insoluble in water, soluble in water and alcohol.
