Chromotrope 2B

Chromotrope 2B CAS: 548-80-1 | MF: C16H9N3Na2O10S2 | MW: 513.37, Buy now for reliable and reproducible results from Tristains at Chemical World.

Chromotrope 2B (CAS: 548-80-1) is an azo dye, dark green to greenish-brown to brown powder, also called 2 (4-Nitrophenylazo)-chromotropic acid disodium salt and Acid Red 176. Having a molecular formula of C16H9N3Na2O10S2, the reagent is very suitable with regard to its good staining properties and dependability in microscopy. The disodium salt form gives it a greater level of solubility and long-term stability leading to its use in histological, microbiological and analytical uses.

Applications

  • The chromotrope 2B results in the combination with AG 1-X8 ion exchange resin during the preconcentration of aluminium and determination with flame atomic absorption spectrometry and ICP-MS.
  • It acts as a stain in the specific cellular and tissue structures enhancing the visualization in the microscope.
  • Being an azo dye, Chromotrope 2B can also serve as a pH indicator, and therefore find application in titrations and other analytical chemistry operations.

Key features

  • Accurate & Dependable: Produces high-quality staining and analysis results.
  • Chemically Stable: Maintains integrity and performance in suitable conditions of storage.
  • Excellent Solubility: Its disodium salt form is easy to dissolve and work within the laboratory.
