phloroglucinol ( phloroglucin stain )
A sweet, crystalline phenol (C 6 H
3 (OH) 3 ) used in
conjunction with hydrochloric acid and alcohol as
a test solution to detect the presence of
mechanical wood pulp in paper, which it turns red.
It has no advantage over the HERTZBERG STAIN other
than that it can be applied directly to the paper.
