Carminic acid appears as dark purplish-brown mass or bright red or dark red powder. Darkens at 248°F. Deep red color in water. Yellow to violet in acidic aqueous solutions. (NTP, 1992)|Carminic acid is a tetrahydroxyanthraquinone that is that is 1,3,4,6-tetrahydroxy-9,10-anthraquinone substituted by a methyl group at position 8, a carboxy group at position 7 and a 1,5-anhydro-D-glucitol moiety at position 2 via a C-glycosidic linkage. It is a natural dye isolated from several insects such as Dactylopius coccus. It has a role as an animal metabolite and a histological dye. It is a tetrahydroxyanthraquinone, a monocarboxylic acid and a C-glycosyl compound. It is a conjugate acid of a carminate(2-).|Coloring matter from the insect Coccus cacti L. It is used in foods, pharmaceuticals, toiletries, etc., as a dye, and also has use as a microscopic stain and biological marker.Basic Info-
