Hi Mark,
I donąt know about the Formulary, but according to this B&S paper
(http://www.bostick-sullivan.com/Technical_papers/all_about_ferric_oxalate.h
tm) theyąve been able to ship oxalic acid free ferric since Œ96. In the
same article, they detail how ferric has different colors based on the
amount of oxalic in it (from amber to green), and I know they sell green
ferric. So B&S must ship both. Not sure about the dry packs.
Hope it helps
Gu
