At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to providing detailed information about the chemicals we supply. Reactive Orange 16, with CAS number 20262-58-2, is a compound of significant interest due to its chemical structure and reactivity. As a disodium salt of a complex naphthalene derivative, its synthesis involves a diazo coupling reaction between a sulfonated aniline derivative and an acetylated naphthol derivative.
The chemical name, disodium 6-acetamido-4-hydroxy-3-[[4-[[2-(sulfooxy)ethyl]sulfonyl]phenyl]azo]naphthalene-2-sulfonate, precisely describes its molecular architecture. This structure contributes to its excellent affinity for cellulosic fibers, making it a cornerstone in reactive dyeing processes. The presence of sulfonate groups enhances its water solubility, which is crucial for effective dye dispersion in aqueous baths.
The preparation of Reactive Orange 16 typically involves the diazotization of 2-[(4-Aminophenyl)sulfonyl]ethyl hydrogen sulfate and its subsequent coupling with 6-Acetamido-4-hydroxynaphthalene-2-sulfonic acid (also known as N-acetyl gamma acid). This meticulously controlled process ensures the high purity of the final product, often exceeding 99%, which is vital for both textile coloration and its role as a pharmaceutical intermediate.
Understanding the physical properties is key for application. Reactive Orange 16 appears as a white solid, and its solubility in water is substantial, particularly at elevated temperatures. While its primary application is in textile dyeing, its potential as a pharmaceutical intermediate makes it a compound of interest for chemical synthesis specialists. Sourcing this high purity azo dye for textiles or as a chemical building block requires a reliable supplier like NINGBO INNO PHARMCHEM CO.,LTD.
Our expertise in sourcing and supplying specialty chemicals ensures that our clients receive products that meet stringent quality standards. Whether you are looking to buy Brilliant orange 3R for your dyeing operations or need a reliable reactive orange 16 supplier China for your research and development, NINGBO INNO PHARMCHEM CO.,LTD. offers a seamless procurement experience.
