Description

Tropaeolin O sodium salt is a reactive dye that possesses the ability to form hydrogen bonds with hydroxyl groups. Tropaeolin O sodium salt has been used in pharmaceutical preparations as a dye for serum and urine samples. It is also used as an indicator for the presence of fatty acids in human serum. The reactive dye is cationic and can be used to detect anionic surfactants, such as sodium dodecyl sulfate, which are commonly found in detergents and soaps. Tropaeolin O sodium salt exhibits synchronous fluorescence when it reacts with hydroxyl ions. This property can be useful for detecting the presence of hydrochloric acid in a sample or identifying p-hydroxybenzoic acid (a product of human metabolism) in urine samples.
