General Description
Coccinic acid, also known as kermesic acid, is an anthraquinone derivative, which is a type of chemical compound prized for its distinct red pigment. Historically, it was primarily extracted from female kermes insects and was used as a dye in multiple applications such as cosmetics, food, and textiles. Typically, it appears as a bright, deep red solid and is soluble in alkaline solutions. Despite its historical usage, it has largely been replaced by other dyes in contemporary times due to cost and availability. Moreover, it is considered toxic and could be harmful if ingested or absorbed through the skin.
