Poison by intravenous, intraperitoneal, and subcutaneous routes. Questionable carcinogen. Mutation data reported. When heated to decomposition it emits toxic fumes of NO_x. See also 2,6-DIAMINOACRIDINE; 3,6-DIAMINOACRIDINE HYDROCHLORIDE HEMIHYDRATE; 3,6-DIAMINOACRIDINE SULFATE (1:1).

 Proflavine (CAS NO.92-62-6), also called proflavin and diaminoacridine, is an acriflavine derivative, a disinfectant bacteriostatic against many gram-positive bacteria. Proflavine is also known to have a mutagenic effect on DNA by intercalating between nucleic acid base pairs. It differs from most other mutagenic components by causing basepair-deletions or basepair-insertions and not substitutions. Proflavine absorbs strongly in the blue region at 445nm (in water at pH 7) with molar extinction coefficient of c. 40,000.
