Sudan IV is a scarlet solid that is practically insoluble in water.
Sudan IV is used as a dye for fat in animal tissue.
The "International Agency for Research on Cancer" (IARC) classifies the dyes Sudan I – IV and Sudan Red 7B as Category 3 cancerogens. Category 3 substances give cause for concern because of their possible carcinogenic effects in humans, but cannot be conclusively assessed due to insufficient information.
