Description

Propyl red is a diacetate that is used in the diagnosis of infectious diseases. The color of propyl red is due to the presence of an acetate group and its affinity for nucleic acids, which allows it to be used as a stain in blood culture. Propyl red has been shown to have a catalytic effect on the oxidation of hydrogen peroxide and can be used as a chromophore in the detection of radiation. The optical properties of propyl red are dependent on pH, with the maximum absorbance at pH 3.5-4.5 and minimum absorbance at pH 7-8.
The molecular weight and protonation state are also important factors for determining optical properties. It has been shown that propyl red can be used to highlight mastitis by visualizing milk fat globules within cells.END>>
