Auramine O, also called Basic yellow 2, Pyocatanium aureum, aizen auramine, Pyoktanin Yellow, Canary Yellow, Pyoktanin, or C.I. 41000, is a diarylmethane dye used as a fluorescent stain. It has the appearance of yellow needle crystals. It can be used to stain acid-fast bacteria (eg. Mycobacterium, where it binds to the mycolic acid in its cell wall) in a way similar to Ziehl-Neelsen stain. It is very soluble in water and soluble in ethanol. It can be used as a fluorescent version of Schiff reagent.
Auramine O can be used together with Rhodamine B as the Truant auramine-rhodamine stain for Mycobacterium tuberculosis. It can be also used as an antiseptic agent.
Its CAS number is [2465-27-2][link] and its SMILES structure is [NH2+]=C (C2=CC=C (N(C)C)C=C2) C1=CC=C(N (C)C)C=C1.
