General description: Picric acid (PA, 2,4,6-trinitrophenol) is a polynitrated aromatic acid. It is strongly acidic in nature. Since it readily dissolves in water, it can easily pollute the environment on exposure. Sensitive detection of PA by tris-imidazolium salt, fluorescent [3+2] self-assembled nanoscopic organic cage and rhodamine based sensors have been reported. It is widely used for the determination of various organic compounds by spectrophotometric and extractive spectrophotometric methods.
Application: Picric acid has been used in the preparation of Bouin′s fixative and picric acid/sodium azide/multi-walled carbon nanotubes.
Application: Picric acid was used in the quantitative determination of bisoprolol.
