Use

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).
