Naphthol AS-D Chemical Properties,Usage,Production

Purification Methods

Purify it by recrystallisation from xylene. This gives yellow-green fluorescent solutions at pH 8.2-9.5. [IR: Schnopper et al. Anal Chem 31 1542 1959.] The naphthol AS-D acetate is obtained with AcCl, m 168-169o, and with chloroacetyl chloride naphthol AS-D-chloroacetate is obtained [Moloney et al. J Histochem Cytochem 8 200 1960, Burstone Arch Pathology 63 164 1957]. [Beilstein 12 H 505.]
