对二甲苯酚橙四钠盐是一种荧光酸性染料，具有络合和螯合特性，可在分光光度法检测和测定金属离子（如钙、镉、铋、锌、铅和汞）中作为指示剂使用。其四钠盐尤其适用于金属滴定的指示剂。它在pH值6.4到10.4之间由黄色变为红色。 它有六个潜在阴离子取代基，其中一个是磺酸盐，在染色条件下和大多数实验室应用中呈阴离子状态。 应用 对二甲苯酚橙已被用作研究骨发育、损失和修复过程中钙化的重要染色剂； 它已被用于碱性磷酸酶的荧光组织化学检测； 它已被用于FBX（亚铁苯甲酸对二甲苯酚橙）凝胶制备，用于研究磁共振成像（MRI）参数对图像质量的影响； 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. Application Xylenol Orange has been used as a vital stain to study calcification in bone development, injury, and repair. It has been used in the fluorescent histochemical detection of alkaline phosphatase. 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.
