It is a derivate of acridine. In histology, it is used as a fluorescent stain, and as a fluorescent probe for non-invasive measurements of cytoplasmic pH changes in whole cells. It is also used as a topical antiseptic. It is usually available as a hydrochloride salt. Its CAS number is [135-49-9] [1] and its SMILES structure is Cc3cc2cc1cc(C)c(N)cc1nc2cc3N. It is a crystalline solid with melting point of 400 °C. Acridine yellow damages DNA and is used as a mutagen in microbiology.
