General description

Picric acid is a polynitrated aromatic acid. It dissolves in water to form a solution with low pH (pH 2.0). It interacts with basic groups of proteins, forms salts and coagulates them. Fixation with picric acid gives a bright stain, but there might be a loss of nucleic acids due to the low pH of the solution.

Application

Picric acid solution can be used as a colorimetric reagent in creatinine determination assay. It is a general cytoplasmic stain, connective tissue fiber stain and a fixative for tissues.
