The material you need is Azo-Xylan (Birchwood). Birchwood xylan is, in fact, a 4-0-methyl-D-glucuronoxylan, with the glucuronic acid occurring as single residues attached to the xylan main chain.
I require 4-0-Methyl-D-Glucurono-D-Xylan-Remazol Brilliant Blue R with a dye content of ~13%. Is Azo-Xylan (Birchwood) (S-AXBL / S-AXBP) suitable?
