[Histonet] Re: Alcian Yellow & Alcian Blue 8GX

[RSRICHMOND <@t> aol.com]

We have a solicitation from Suzhou Sinoera Chem Co. in Suzhou New & Hi-Tech 
District in China about various Alcian dyes. (Actually they spam me every month 
or so with similar advertisements.)

Many of you have been following Dick Dapson's efforts at Anatech to develop 
environmentally safe processes for making these dyes, after the original German 
manufacturer stopped making them because they found the synthetic 
intermediates too hazardous to handle. Anatech now offers environmentally safely 
synthesized Alcian blue, but not the other dyes (unless I'm behind in my reading).

Does Suzhou Sinoera use synthetic methods that are safe for workers and for 
the environment? 

(I have no connection with Anatech or with Suzhou Sinoera.)
