1-Naphthyl acetate Usage And Synthesis

Chemical Properties

1-Naphthyl acetate is white to light yellowish or slightly pink

Uses

1-Naphthyl acetate is usually used in a rapid staining method for identification of macrophages; counts by this method were confirmed by the more complex morphological criteria, by phagocytosis, and by the presence of Fc receptors.

Synthesis Reference(s)

Synthetic Communications, 21, p. 989, 1991 DOI: 10.1080/00397919108019787
Tetrahedron Letters, 30, p. 95, 1989 DOI: 10.1016/S0040-4039(01)80332-4

Purification Methods

Chromatograph the acetate on silica gel and crystallise as the 2-isomer below. The 2,4,7-trinitrofluoren-9-one complex has m 120o (from EtOH). [Beilstein 6 H 608, 6 III 2928, 6 IV 4217.]
