In the realm of organic chemistry, intermediates are the bedrock upon which complex molecules are built. 4-Bromoaniline (CAS No. 106-40-1) is one such fundamental compound, highly valued for its role in both sophisticated organic synthesis and as a key precursor in industrial chemical processes, most notably azo dye manufacturing.
Chemically, 4-Bromoaniline is an aromatic amine where a bromine atom is substituted at the para position of the aniline ring. This structure imparts specific reactivity, making it an excellent starting material for various chemical transformations. Its molecular formula is C6H6BrN, with a molecular weight of 172.03 g/mol. A crucial specification for its use is its purity, which is typically required to be ≥99.0% for most industrial applications. The substance is commonly observed as an off-white to brown solid, with its precise color potentially varying slightly based on its manufacturing batch and purity.
The utility of 4-Bromoaniline extends across several sectors. As an intermediate for azo dye manufacture, it contributes to the creation of a wide spectrum of colors used in textiles, printing, and paints. Beyond dyes, it serves as a building block in the synthesis of pharmaceuticals, agrochemicals, and other fine organic chemicals. Researchers and product formulators often seek to buy 4-Bromoaniline for its versatile reactivity in reactions like Sandmeyer reactions or its use in forming amide linkages.
For procurement professionals and researchers looking to purchase 4-Bromoaniline, understanding its handling and storage is vital. It should be stored in a cool, dry, and well-ventilated area, away from incompatible substances such as strong oxidizers and acids. Proper personal protective equipment (PPE) should be used when handling, given its potential irritant properties. As a trusted chemical supplier, NINGBO INNO PHARMCHEM CO.,LTD. provides 4-Bromoaniline with detailed safety information and ensures adherence to international quality standards.
When evaluating 4-Bromoaniline suppliers, compare their product specifications, pricing, and reliability. Securing a consistent supply of high-purity 4-Bromoaniline at a competitive price from a reputable manufacturer in China is key to ensuring the efficiency and quality of your downstream processes.
