Carminic Acid Usage And Synthesis

Chemical Properties	red to dark red crystalline powder
Uses	A red glucosidal hydroxyanthrapurin, it is produced naturally within some insects as a defense mechanism.
Uses	antineoplastic, glucosyltransferase inhibitor
Definition	ChEBI: 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-gly osidic linkage. It is a natural dye isolated from several insects such as Dactylopius coccus.
General Description	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.
Air & Water Reactions	Soluble in water [Hawley].
Reactivity Profile	CARMINE neutralizes bases in exothermic reactions. Incompatible with strong oxidizing agents.
Fire Hazard	Flash point data for CARMINE are not available. CARMINE is probably combustible.
Purification Methods	Carminic acid forms red prisms from EtOH. It gives a red colour in Ac2O and yellow to violet in acidic solution. UV: max (H2O) 500nm ( 6,800); (0.02N HCl) 490-500nm ( 5,800) and (0.0001N NaOH) 540nm ( 3,450). IR: max (Nujol) 1708s, 1693s, 1677m, 1648m, 1632m, 1606s, 1566s, 1509 cm-1. Periodate oxidation is complete after 4hours at 0o with the consumption of 6.2 mols. The tetra-O-methyl carminate has m 186-188o (yellow needles from *C6H6/pet ether).
