It is the standard dye in North American for sta ning collagen and is also used extensively in plant histology.

Preparation

Benzaldehyde (1 Moore) and N-benzyl-N-ethylbenzenamine (2 Moore) condensation, and then three stlfonation, and will product oxidation and will last them into sodium salt.

Properties and Applications

green. SAP green powder. Easy to dissolve in water (a blue light green), and very difficult to soluble in alcohol. Strong sulfuric acid in orange, yellow is diluted. Dye with sodium hydroxide solution nearly colorless, has the purple precipitation.
