Rafael Badalyan, MD in Yerevan, Armenia (OK, guys, go look at the map if you 
don't know where Armenia is) is trying to find Biebrich scarlet.

About all I can help with is the correct spelling and some synonyms. 
According to Lillie's H.J. Conn, Biebrich scarlet (Colour Index 26905) is 
also called 
acid Red 66, Croceine scarlet, Scarlet B, Scarlet EC, Scarlet 3B (FIAT), 
Double Scarlet BSF, and Ponceau B, 3RP.

Dick Dapson at ANATECH undoubtedly knows about its current availability.
