:Acid Orange 7
Description:
Acid Orange 7, also known as Orange II, is an azo dye commonly used in various applications, including textiles, food, and cosmetics. It is characterized by its bright orange color and is soluble in water, making it suitable for dyeing processes. The chemical structure of Acid Orange 7 features an azo group (-N=N-) that connects two aromatic rings, contributing to its color properties. This compound has a relatively low molecular weight and exhibits good stability under normal conditions, although it can be sensitive to light and heat. Acid Orange 7 is classified as a synthetic dye and is often used in acidic dyeing processes due to its affinity for protein fibers. However, it is important to note that some azo dyes, including Acid Orange 7, have raised environmental and health concerns, leading to regulatory scrutiny in certain regions. As such, its use may be restricted or monitored in specific applications to ensure safety and compliance with environmental standards.

CAS:<p>Acid Orange 7 is a reactive dye that is used in wastewater treatment. It has an orange color and has been shown to adsorb to cell nuclei and human serum. Acid Orange 7 reacts with the reaction solution to form a decolorized product, which can be seen using synchronous fluorescence. The Langmuir adsorption isotherm for this dye shows that the optimum concentration of Acid Orange 7 is 0.5%. Acid Orange 7 has carcinogenic potential due to its ability to bind DNA, which may lead to mutations in cells. Electrochemical impedance spectroscopy studies have shown that this dye binds covalently with proteins, which may also result in mutagenic effects.</p>Formula:C16H11N2NaO4SPurity:Min. 95%Color and Shape:Red PowderMolecular weight:350.33 g/molOrange 2 sodium 100 µg/mL in Water
