CAS 3709-43-1: 4,4′-Dinitro-2,2′-stilbenedisulfonic acid disodium salt

Description: 4,4′-Dinitro-2,2′-stilbenedisulfonic acid disodium salt, with the CAS number 3709-43-1, is a synthetic organic compound characterized by its structure, which includes two nitro groups and sulfonic acid functionalities attached to a stilbene backbone. This compound is typically used as a fluorescent dye and is known for its ability to absorb light in the ultraviolet-visible spectrum, making it useful in various analytical applications, including fluorescence microscopy and as a tracer in biological studies. It is soluble in water due to the presence of sulfonate groups, which enhance its ionic character. The disodium salt form indicates that it can dissociate in solution, contributing to its ionic properties. Additionally, the compound exhibits stability under normal conditions but may undergo degradation when exposed to strong acids or bases. Its unique properties make it valuable in research and industrial applications, particularly in the fields of biochemistry and materials science. Safety precautions should be observed when handling this compound, as it may pose health risks if ingested or inhaled.
