Naphthol AS Acetate（3-Acetoxy-2-naphthanilide） is a reactive chemical that reacts with basic dyes, crosslinkers, and other compounds. It has been used in the treatment of lymphocytic leukemia cells in vitro.
3-Acetoxy-2-naphthanilide also inhibits the enzyme activities of acetylcholinesterase and phosphatases, suggesting that it may be useful for treating myelogenous leukemias. 3-Acetoxy-2-naphthanilide is also used to dye agarose gels in order to visualize DNA bands during electrophoresis.
Recrystallise it from hot MeOH and dry in vacuo over P2O5. It has m 252o after sublimation at 210-215o. It is slightly soluble in AcOH, EtOH, CHCl3 or *C6H6. It is a fluorogenic substrate for albumin esterase activity. [Chen & Scott Anal Lett 17 857 1984.] At 320nm it has fluorescence at 500nm. ex em [Brass & Sommer Chem Ber 61 1000 1928, Beilstein 12 II 260, 12 III 960, 12 IV 923.]
