The Romans used Tyrian purple
to prove that class distinction existed.
Marine gastropods of the family Muricidae produce Tyrian purple (6,6'-dibromoindigo; Cooksey 2001), a dye of significant historical importance that can be obtained from no other natural source (Westley & Benkendorff 2008).
2011), as is the case for some of the bioactive brominated indole precursors of Tyrian purple (Benkendorff 2013).
The biosynthetic origin of Tyrian purple which has been exclusively isolated from Muricidae molluscs is not currently known.
Alexander the Great (when giving imperial audiences as emperor of the Macedonian Empire), the emperors of the Seleucid Empire, and the kings of Ptolemaic Egypt wore Tyrian purple.
The imperial robes of Roman emperors were Tyrian purple trimmed in gold thread, while the badge of office for a Roman Senator was a stripe of Tyrian purple on a white toga.

One was Tyrian purple

The effect of periodically "milking" to obtain Tyrian Purple
from Plicopurpura pansa (Gould, 1853) on the frequency of expulsion and mortality.
Photolysis of tyriverdin gives dibromoindigo, the main component of Tyrian purple, and the odorous dimethyl disulfide (Cooksey 2001).
After the main chemical routes leading to Tyrian purple were described the question about the biologic role of the hypobranchial secretions still remains open.
