| Physical and Chemical Properties | Physicochemical properties Malachite green is soluble in water and ethanol. It is a dark green crystal made by one molecule of benzaldehyde and two molecules of N,N-dimethylaniline condensed in hydrochloric acid or sulfuric acid to form a recessive base of tetramethyldiaminotriphenylmethane, which is oxidized by lead dioxide in acidic medium. It is named after its appearance color is malachite green. Malachite green is mostly prepared in the form of oxalate (malachite green oxalate/C23H25N2 HC2O 4 -) and sold on the market. Hydrochloride (malachite green chloride/C23H25 N 2 Cl-) is relatively rare. Malachite green hydrochloride is an industrial-grade chemical substance, which is a double zinc salt synthesized by adding zinc chloride in the production process of malachite green. In aqueous solution, malachite green cation (colored form) combines with active hydroxide ion to form non-ionized colorless alcohol base, which has high lipophilicity. Therefore, it is believed that malachite green may invade cells in the form of alcohol base. |
