Descrição

Descrição geral

Xylenol Orange tetrasodium salt is a fluorochrome acid dye with complexing and chelating properties that make it useful as an indicator in the spectrophotometric detection and assay of metal ions such as calcium, cadmium, bismuth, zinc, lead, and mercury. Its tetrasodium salt especially is used as an indicator in metal titrations. It changes color from yellow to red between pH 6.4 to 10.4. It has six potentially anionic substituents, one being sulfonate, and is anionic under staining conditions and during most laboratory applications.[1][2]

Aplicação

• Xylenol Orange has been used as a vital stain to study calcification in bone development, injury, and repair.[1]
• It has been used in the fluorescent histochemical detection of alkaline phosphatase.[1]
• It has been used in FBX (ferrous benzoic xylenol orange) gel preparation to study the effects of MRI (magnetic resonance imaging) parameters on image quality.
