Chromotrope 2R

Description:

Chromotrope 2R, with the CAS number 4197-07-3, is a synthetic dye belonging to the azo dye class, characterized by its vibrant red color. It is primarily used in various applications, including textile dyeing, paper coloring, and as a biological stain in microscopy. The dye exhibits good solubility in water, which makes it suitable for aqueous applications. Chromotrope 2R is known for its stability under light and heat, although, like many azo dyes, it may undergo degradation under extreme conditions. Its chemical structure features azo (-N=N-) linkages, which are responsible for its color properties. While it is effective for its intended uses, safety considerations are important, as some azo dyes can release aromatic amines upon degradation, which may pose health risks. Therefore, handling Chromotrope 2R requires adherence to safety guidelines to minimize exposure. Overall, Chromotrope 2R is valued for its coloring properties in various industries, but awareness of its chemical behavior and safety profile is essential.

Chromotrope 2R

CAS: 4197-07-3

Chromotrope 2R is a chromogenic substrate that is used to assay protothecosis. Phase chromatography of this compound produces two different zones: one that is blue and another that is yellow-green. The blue zone indicates the presence of phosphotungstic acid, which can be used as a diagnostic marker for protothecosis. The yellow-green zone indicates the presence of keratinization, which can be used as a diagnostic marker for protothecosis. Chromotrope 2R has also been shown to inhibit keratinization in tissues, leading to a lack of staining and cellular changes in the surrounding tissue.
Prototheca species are filamentous eukaryotic organisms that produce a variety of polyketides and other secondary metabolites. These compounds are toxic to animals when ingested and can lead to hemorrhagic necrosis in both humans and animals. Protothecosis is caused by infection with Prototheca zopfii or Prototheca w
