NAPHTHOL AS ACETATE Usage And Synthesis

Purification Methods

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.]
