Description

General description

Azophloxine, also known as acid red 1 (AR 1), is a member of synthetic red azo dye family. Azo dye is an organic dye with good photo-thermal stability, dissolvability and easy preparation feature. In addition, it also has noticeable third order nonlinearity and good optical power limiting properties. It has been used as a real acid counterstain in light and fluorescence microscopy. Azophloxine also facilitates the determination of proteins and peptides.

Application

Azophloxine has been used as a dye in Von Kossa staining and nonlinear optical studies. It is also used in photocatalytic tests.
