In the realm of industrial chemistry, certain molecules serve as foundational elements, enabling the creation of a vast array of essential products. 3-Aminophenol (CAS: 591-27-5) is one such indispensable compound, celebrated for its dual importance as a key intermediate in pharmaceutical synthesis and a critical component in the production of azo dyes. NINGBO INNO PHARMCHEM CO.,LTD. is a dedicated supplier of this versatile chemical, supporting innovation and production across these vital sectors.

The pharmaceutical industry relies heavily on precisely synthesized intermediates to produce life-saving and life-enhancing medications. 3-Aminophenol plays a significant role here, most notably as a precursor for 5-aminosalicylic acid (5-ASA). 5-ASA is a cornerstone in the treatment of inflammatory bowel diseases, including ulcerative colitis and Crohn's disease, managing symptoms and improving patient quality of life. The efficacy and purity of the final drug product are directly influenced by the quality of its intermediates. Therefore, the consistent high purity (≥99.0% by HPLC) of 3-Aminophenol supplied by NINGBO INNO PHARMCHEM CO.,LTD. is critical for pharmaceutical manufacturers.

In addition to its pharmaceutical utility, 3-Aminophenol is a vital component in the synthesis of azo dyes. Azo dyes represent the largest class of synthetic organic dyes, utilized extensively in industries such as textiles, leather, paper, and food coloring. The characteristic azo group (-N=N-) is formed through diazotization and coupling reactions, and 3-Aminophenol, with its reactive amino and hydroxyl functionalities, serves as an excellent coupling component or a precursor to diazo components. Its ability to participate in these reactions leads to dyes with a wide range of colors and good fastness properties. Manufacturers of azo dyes depend on the reliable supply of intermediates like 3-Aminophenol to ensure consistent product quality and efficient production cycles.

The chemical properties of 3-Aminophenol, such as its appearance as an off-white crystalline powder and its specific melting point, are important considerations for its handling and processing in industrial settings. Proper storage, typically in a cool, ventilated place, helps maintain its integrity. The chemical structure of 3-Aminophenol allows it to undergo various reactions, including electrophilic aromatic substitution, oxidation, and diazotization, making it a versatile tool for synthetic chemists. NINGBO INNO PHARMCHEM CO.,LTD. provides comprehensive technical specifications to assist clients in optimizing their use of this chemical.

The importance of 3-Aminophenol in both the pharmaceutical and dye industries underscores its broad impact on global commerce and health. By providing a reliable source of high-quality 3-Aminophenol, NINGBO INNO PHARMCHEM CO.,LTD. empowers manufacturers to develop innovative products, from advanced medical treatments to vibrant textile dyes. Understanding the specific CAS number, 591-27-5, is key to sourcing the correct material for these diverse industrial applications.
