In the realm of fine chemicals, understanding the specific properties and applications of key intermediates is vital for research scientists and procurement managers. 4'-Aminoazobenzene-4-sulphonic acid, identified by its CAS number 104-23-4, is one such compound that plays a significant role in various industrial synthesis processes, most notably in the production of dyes. As a premier supplier, we aim to provide clarity on this important chemical.

The compound, typically appearing as a light orange-red powder, possesses a molecular formula of C12H11N3O3S and a molecular weight of 277.3. Its structure includes an amino group, an azo linkage, and a sulphonic acid group, which contributes to its reactivity and solubility. These functional groups make it an ideal precursor for the synthesis of azo dyes, which are extensively used in the textile industry, as well as in inks and pigments.

For professionals seeking to purchase this chemical, understanding its role as a dye intermediate is key. The sulphonic acid group enhances water solubility, making it easier to handle in aqueous reaction systems, while the azo group is fundamental to the chromophore responsible for color in the final dye product. This versatility makes it a valuable component for any formulation requiring specific color properties.

When looking to procure CAS 104-23-4, partnering with a reliable manufacturer is essential. Companies that buy in bulk from experienced Chinese chemical producers can often secure better pricing and ensure a consistent supply. This strategic sourcing allows R&D scientists to focus on formulation and application development, confident in the quality and availability of their raw materials.
