1902, Ernest John Parry, John Henry Coste, The Chemistry of Pigments, page 202:These have been termed cochinic acid C9H8O5, a body very soluble in alcohol, but nearly insoluble in water, melting at 293° with decomposition : and cochinelic acid, C10H8O7, which forms crystalline needles melting at 224° to 225°.
1909, Journal of the Chemical Society, page 486:When heated with sulphuric acid, this dicarboxylic acid forms cochinelic acid and carbon dioxide.
1922, Victor von Richter, Richard Anschütz, Georg Schroeter, Organic Chemistry: Or, Chemistry of the Carbon Compounds:...on heating with concentrated H2SO4, decomposes into CO and the so-called cochinelic acid , C10H8O7.
