p-Naphtholbenzein

CAS: 145-50-6

p-Naphtholbenzein is a fluorescent dye that is used in the diagnosis of human pathogens. It can be used to detect the presence of fatty acids, which are found on the surface of bacteria and in the cell wall. p-Naphtholbenzein elutes from an agar plate at pH 6.0 and can be detected using a spectrophotometer. The fluorescence of p-naphtholbenzein is absorbed by fatty acids, which emit light when excited by ultraviolet light. This makes it useful for detecting fatty acid content in cells, organisms, and surfaces. It is also used as an excipient in subclinical mastitis treatments to help reduce inflammation and improve milk production. In biodiesel reactions, p-naphtholbenzein acts as an optimal reaction catalyst because it stabilizes hydroxybenzoic acid (HBA) with benzalkonium chloride (BZK).
