Reddish brown shiny crystalline powder
- Xylenol orange sodium salt is a triphenylmethane color developer. The scientific name is “3,3 ‘- bis (n, n-dicarboxymethyl aminomethyl) – o-cresol sulfonphthalein”. The molecular formula is c31h32n2o13s. Molecular weight 672.66. Reddish brown shiny crystalline powder. Deliquescent easily. Its sodium salt is easily soluble in water, but insoluble in alcohol and ether. Due to the structure of o-methylphenolphthalein, the pH value of the solution has a great influence on its color change. When pH > 6.3, the solution shows red, and when pH < 6.3, it shows yellow.
- Xylenol orange sodium salt and most metal ions can form red purple complexes. Therefore, when used as a metal indicator for Complexometric titration, it is suitable for acidic solutions with pH < 6. It is used to determine metal ions such as bismuth, thorium, scandium, lead, zinc, lanthanum, cadmium and mercury. The reagent is often prepared into 0.5% aqueous solution, which is stable and can be maintained for 2 ~ 3C chemicalbook weeks. In addition, it can also be used as a chromogenic agent for colorimetric analysis. For example, in hydrochloric acid medium, it forms orange complex with niobium, with maximum absorption wavelength λ Max is about 520 ~ 530 nm, and the maximum absorption wavelength of the reagent itself λ Max is about 434 ~ 460 nm, which is used for the determination of Trace Niobium in ore samples and steel.
The production base is located in Zhangqiu chemical industry park and Tai’an high-tech chemical industry park. laboratory and workshop in strict accordance with the GMP standard and the product fit national ISO9001 and ISO2000 standards.
“Zhishang” products are exported to Europe, North and South America, the Middle East, Asia Pacific and Africa area, so as to establish a long-term and stable cooperation relationship with customer in the world.
