Frequently Asked Questions
Sudan II is primarily used for dyeing non-polar substances such as fuels, lubricants, waxes, and plastics, as well as serving as a histological stain for detecting lipids in laboratory microscopy.
No, Sudan II is insoluble in water, alkali, and ebb acid. It is specifically designed to dissolve in organic solvents like ether, naphtha, and various fats and oils.
It should be stored in a cool, dry, and well-ventilated area, kept in tightly sealed containers away from strong oxidizing agents and direct sunlight.
Due to potential carcinogenicity, Sudan II is banned for use in food products in many countries. Its modern applications are strictly limited to industrial and research purposes.
The standard industrial packing is 25kg per fibre drum, ensuring stability and protection during long-distance transport.
While all are lipophilic azo dyes, they differ in their specific chemical structures, which results in slight variations in color shade and staining affinity for different types of lipids.
