The chemical industry is built upon a foundation of specialized compounds that enable the creation of countless everyday products. Among these, chemical intermediates serve as the essential building blocks for more complex substances. 4,4'-Diaminobenzenesulphanilide, identified by its CAS number 16803-97-7, is a prime example of such a foundational chemical, particularly vital within the dye manufacturing sector. As a manufacturer and supplier committed to providing high-quality chemical solutions, we understand the importance of detailing the roles and benefits of compounds like this for our B2B clients, including procurement managers and research scientists.

A Key Intermediate for Vibrant Dyes

The primary industrial application of 4,4'-Diaminobenzenesulphanilide is its use as a precursor in the synthesis of azo dyes, specifically for producing certain shades of black and brown. It is indispensable for the production of widely used dyes such as Acid Black 210 and Acid Black 234. These dyes are critical for coloring a variety of materials, including textiles, leather, and paper, where color fastness and depth are essential. The compound’s chemical structure, featuring two reactive amino groups and a sulfonamide linkage, makes it highly effective in coupling reactions required for azo dye formation. Its importance is further amplified by its status as a preferred alternative to benzidine derivatives, which are recognized for their potential health hazards. By opting for 4,4'-Diaminobenzenesulphanilide, manufacturers can ensure product quality while enhancing workplace safety and environmental compliance.

Chemical Properties and Specifications for Procurement

For professionals looking to buy 4,4'-Diaminobenzenesulphanilide, understanding its key chemical and physical properties is fundamental. The compound’s molecular formula is C12H13N3O2S, with a molecular weight of 263.32 g/mol. It is typically supplied as a white crystalline powder, a characteristic that facilitates its handling and integration into various manufacturing processes. A crucial specification for industrial procurement is its purity, which is generally guaranteed to be a minimum of 98%. This high purity ensures the reliability and predictability of the chemical reactions in which it is used, leading to consistent dye quality. When engaging with suppliers, always request the Certificate of Analysis (COA) to verify these specifications. Reliable manufacturers, especially those in China, often provide these details upfront and can supply the product in various packaging options, such as 25 kg drums, suitable for industrial use.

Sourcing Strategies for Industrial Buyers

When sourcing 4,4'-Diaminobenzenesulphanilide (CAS 16803-97-7), buyers should prioritize manufacturers and suppliers known for their consistent quality, competitive pricing, and reliable delivery. Establishing a direct relationship with a manufacturer can offer significant advantages, including better pricing for bulk orders and direct access to technical support. Online chemical directories and platforms can be valuable tools for identifying potential suppliers and comparing their offerings. It is also advisable to conduct thorough due diligence, including checking supplier reviews and requesting product samples for in-house testing before committing to a large purchase. As a dedicated provider of fine chemicals, we strive to be a trusted partner, offering 4,4'-Diaminobenzenesulphanilide that meets stringent industry standards and supports the success of our clients' operations.
