Wang Lian MD, Medical School of Nanjing University in China, asks whether Biebrich Scarlet is Acid Red 66 or Acid Red 73.
According to R.D. Lillie (both Histologic Technic 3rd ed. and Conn's Biological Stains 9th ed) states that the 2nd edition of the Colour Index (a rare book I have never seen a copy of) refers to Biebrich scarlet as Acid Red 66.
