Naphazoline hydrochloride nitrate

Use. Naphazoline hydrochloride and nitrate are used as 0.05 to 0.1% aqueous solutions. [Pg.799]

An aqueous solution of naphazoline hydrochloride (1 in 100) is treated with 6N ammonium hydroxide to precipitate naphazoline base. Ilie filtrate then yields a white, curdy precipitate upon the addition of O.IN silver nitrate. The precipitate is insoluble in nitric acid but is soluble in a slight excess of 6N ammonium hydroxide - . ... [Pg.328]

An adaptation of the USP TLC procedure for the determination of ordinary impurities in naphazoline hydrochloride allowed for the detection of 1-naphthylacetylethylenediamine in the presence of naphazoline. Using silica gel 60 high-performance TLC plates (20 X 20 cm) and a mobile ph of methanol-glacial acetic add-purified water (8 1 1, v/v/v), spots were visible after spraying with ninhydrin naphazoline Rf - 0.54 1-naphthylacetyl-ethylenediamine Rf - 0.63. A similar method has been described in the European Pharmacopoeia for 1-naphthylacetylethylenediamine in naphazoline nitrate S. [Pg.330]
