Description

Bromocresol purple sodium salt is a dye that emits light when it is irradiated with light of a particular wavelength. It has been used to detect amniotic fluid contamination in the laboratory and as an absorber in polymer films. Bromocresol purple sodium salt absorbs ultraviolet and visible light, which causes it to emit red light. The molecules of bromocresol purple sodium salt are long-chain triazoles, which absorb water vapor and emit infrared radiation. This property can be used to detect the presence of alkali metals. The luminescent property of bromocresol purple sodium salt can be enhanced by adding an alkali metal, such as potassium or lithium chloride, to the solution where it is dissolved.
