== Signifigance of Indigo Pure BASF in Indanthrene Blue ==
The color and vat dye that came before Indanthrene Blue was Indigo Pure BASF. This synthesis consisted of Phenylglycocoll acid mixed and fused with Caustic soda which transforms into an alkaline solution. When this Alkaline solution makes contact with oxygen, the color Indigo precipitates/appears. This process would be replicated in various ways to create Indanthrene blue and its derivatives. Indigo Pure BASF contributed to the research as a cornerstone of its progress as the chemists at BASF took 17 years to research and synthesize this vat dye.Gesellschaft Deutscher Chemiker.
