Re: A dye by any name would stain as red?

From:Nancy E Weber

I have a Basic Fuchsin Hydrochloride bottle from JT***** and its catalog #
is B660-03, its C.I. # is 42510, its CAS # is 632-99-5. I don't know when
this bottle was ordered, but personally I've always ordered by the company
catalog #. I would go with the Basic Fuchsin Hydrochloride.
