Benzenesulfonic acid, 2-[2-(2-hydroxy-1-naphthalenyl)diazenyl]-5-[2-(4-sulfophenyl)diazenyl]-, sodium salt (1:2)

Description:

Benzenesulfonic acid, 2-[2-(2-hydroxy-1-naphthalenyl)diazenyl]-5-[2-(4-sulfophenyl)diazenyl]-, sodium salt (1:2), commonly referred to as a type of azo dye, is characterized by its complex molecular structure that includes multiple aromatic rings and functional groups. This compound typically exhibits vibrant colors due to the presence of the azo (-N=N-) functional group, which is known for its ability to absorb visible light. The sulfonic acid groups contribute to its solubility in water, making it suitable for various applications in dyeing and as a pH indicator. The presence of hydroxyl and sulfonyl groups enhances its reactivity and stability in different chemical environments. Additionally, this compound may exhibit properties such as high thermal stability and resistance to fading, which are desirable in dye applications. Its sodium salt form indicates that it is likely used in aqueous solutions, facilitating its use in various industrial and laboratory settings. Safety and handling precautions should be observed due to potential toxicity associated with azo compounds.

Biebrich scarlet

CAS: 4196-99-0

Biebrich scarlet is a basic protein obtained from the blood of pregnant women. It is used in wastewater treatment, where it acts as a coagulant and flocculent to remove organic material. Biebrich scarlet also has been shown to inhibit the growth of bacteria by binding to cell nuclei, preventing DNA synthesis. This protein is found in human serum and biological samples and has been used in experimental models for bowel disease. Biebrich scarlet is a glycol ether that reacts with benzalkonium chloride to form a surface methodology that has been used for detection of radiation.
