For procurement managers in the textile and chemical industries, securing a consistent and high-quality supply of essential intermediates is paramount. Among these, 4-Chloro-3-nitrobenzenesulfonamide (CAS 97-09-6) stands out as a vital component in the synthesis of a broad spectrum of azo dyes. This article serves as a comprehensive guide for buyers looking to source this critical chemical, focusing on its applications, quality considerations, and the benefits of partnering with reputable manufacturers and suppliers in China.

Understanding 4-Chloro-3-nitrobenzenesulfonamide: The Backbone of Azo Dyes

4-Chloro-3-nitrobenzenesulfonamide, with the CAS number 97-09-6, is a chemical compound characterized by its yellow crystalline appearance. Its molecular formula, C6H5ClN2O4S, and molecular weight of 236.63 indicate its specific chemical structure, which lends itself to crucial roles in organic synthesis. The primary application for this compound is as a key intermediate in the production of azo dyes. These dyes are widely utilized across various industries, most notably in textiles, due to their vibrant color range, good fastness properties, and cost-effectiveness. For product formulators and R&D scientists, understanding the purity and consistency of this intermediate is essential for achieving desired color shades and performance characteristics in their final dye products.

Key Considerations When Purchasing

When a procurement manager or R&D scientist searches to buy 4-Chloro-3-nitrobenzenesulfonamide, several factors come into play. Firstly, purity is a critical specification. Most manufacturers will offer a purity level of 97% or higher, which is generally sufficient for dye synthesis. However, for specialized applications, higher purity grades might be sought. Secondly, understanding the application is key. Knowing that it's primarily a dyestuff intermediate helps in evaluating suppliers and ensuring they cater to industrial-scale needs.

Furthermore, the CAS number (97-09-6) serves as a unique identifier, crucial for accurate product identification and regulatory compliance. When searching for a 4-Chloro-3-nitrobenzenesulfonamide supplier, particularly from China, it is advisable to look for manufacturers with established export capabilities and a track record of reliable service. This includes checking for free sample availability, competitive pricing, and clear communication channels.

Sourcing Strategies: Partnering with Chinese Manufacturers

China has emerged as a global hub for chemical manufacturing, offering a vast array of intermediates at competitive prices. For businesses looking to procure 4-Chloro-3-nitrobenzenesulfonamide, partnering with a reputable manufacturer in China can yield significant cost savings and supply chain advantages. When engaging with Chinese suppliers, it is important to verify their quality control processes, production capacity, and logistical support. Many leading Chinese chemical companies are well-equipped to handle international orders, providing necessary documentation such as Certificates of Analysis (CoA) and Safety Data Sheets (SDS).

For those seeking to secure a stable supply, establishing a long-term relationship with a qualified supplier is beneficial. This can involve regular inquiries for price updates and exploring bulk purchase discounts. By leveraging the robust chemical manufacturing infrastructure in China, companies can ensure they obtain high-quality 4-Chloro-3-nitrobenzenesulfonamide at favorable terms, thereby optimizing their production costs and enhancing their competitive edge in the market.

In conclusion, 4-Chloro-3-nitrobenzenesulfonamide is an indispensable intermediate for the azo dye industry. By understanding its properties, applications, and employing effective sourcing strategies, procurement professionals can secure a reliable supply from qualified manufacturers and suppliers, ensuring the continued success of their product development and manufacturing operations.
