Description
Acid Yellow 36 is an industrial azo dye used in textiles, leather, and paper, but should not be used in foods or cosmetics due to toxicity concerns. Metanil yellow changes its color from red at 1.2 pH to yellow at pH 2.5 and has been used as a pH indicator. Metanil yellow is used as a counterstain for microscopy sections, for staining of leukocyte granules, or as a counterstain in PAS (periodic acid-Schiff)/iron-hematoxylin stained sections to increase contrast. Spectral Data: λmax ~415 nm.
