CAS 547-57-9
:C.I. Acid Orange 6
Description:
C.I. Acid Orange 6, with the CAS number 547-57-9, is a synthetic azo dye commonly used in various applications, including textiles, food, and cosmetics. This compound is characterized by its vibrant orange color, which results from the presence of azo functional groups (-N=N-). It is water-soluble, making it suitable for use in aqueous solutions. The dye exhibits good lightfastness and stability under acidic conditions, which is advantageous for its application in dyeing processes. However, like many azo dyes, it may raise environmental and health concerns due to the potential release of aromatic amines upon degradation. Therefore, its use is often regulated in certain industries. In terms of chemical structure, C.I. Acid Orange 6 contains sulfonic acid groups that enhance its solubility and affinity for various substrates. Overall, while it is effective for coloring purposes, considerations regarding safety and environmental impact are essential when utilizing this dye in commercial products.

CAS:Tropaeolin O sodium salt is a reactive dye that possesses the ability to form hydrogen bonds with hydroxyl groups. Tropaeolin O sodium salt has been used in pharmaceutical preparations as a dye for serum and urine samples. It is also used as an indicator for the presence of fatty acids in human serum. The reactive dye is cationic and can be used to detect anionic surfactants, such as sodium dodecyl sulfate, which are commonly found in detergents and soaps. Tropaeolin O sodium salt exhibits synchronous fluorescence when it reacts with hydroxyl ions. This property can be useful for detecting the presence of hydrochloric acid in a sample or identifying p-hydroxybenzoic acid (a product of human metabolism) in urine samples.Formula:C12H9N2O5SNaPurity:Min. 95%Color and Shape:PowderMolecular weight:316.27 g/molAcid Orange 6
