Aplysioviolin, along with the other components of sea hare ink, has been utilized as a dye since antiquity.
Aplysioviolin in particular has been implicated in classical-age dyeing, and has recently been the subject of investigation as the ancient tekhelet (תְּכֵלֶת) dye of Hebrew and other Mediterranean civilizations, though it remains one of several possible historical contenders.
Aplysioviolin was first specifically isolated and characterized as a pH-dependent color-changing zoochrome by Lederer & Huttrer in 1942.
A first structure was proposed by Rüdiger in 1967 using a chromic-acid based microdegredation technique.
This technique was similarly applied in the years following to characterize the structures of the related compounds phycoerythrobilin and phycocyanobilin.
The 1967 proposed structure was later modified to remove an angular hydroxyl group at the 7' position, and the final structure was given by Rüdiger & O'Carra in 1969.
