For procurement professionals in the chemical and textile industries, securing a consistent and high-quality supply of essential raw materials is paramount. 2,5-Diaminobenzenesulfonic acid (CAS 88-45-9) is one such critical intermediate, primarily used in the synthesis of various industrial dyes. This guide focuses on helping B2B purchasing managers identify and select the most reliable suppliers and manufacturers for this vital compound.

Understanding the Needs: The Role of 2,5-Diaminobenzenesulfonic Acid

2,5-Diaminobenzenesulfonic acid serves as a key precursor in the production of direct dyes such as Direct Blue 176 and Direct Black 32, which are widely employed in textile dyeing. Its chemical structure, featuring amino and sulfonic acid groups, dictates its reactivity and solubility, making it indispensable for achieving specific color properties and application performance. The typical purity requirement is a minimum of 98% assay, ensuring optimal results in downstream synthesis processes.

Key Criteria for Selecting a Supplier

When searching for a 2,5-diaminobenzenesulfonic acid supplier, purchasing managers should prioritize the following:

  • Quality Assurance: Look for suppliers who provide a Certificate of Analysis (CoA) confirming the 98%min purity. Consistent quality is non-negotiable for manufacturing processes.
  • Product Specifications: Ensure the product meets all necessary technical specifications for your intended application.
  • Manufacturing Capabilities: A strong manufacturer will have robust production processes and capacity to meet your volume needs.
  • Competitive Pricing: Obtain quotes and compare pricing for bulk purchases to ensure cost-effectiveness. Searching for 'CAS 88-45-9 dye precursor price' can provide valuable market insights.
  • Reliability and Delivery: Assess the supplier's track record for on-time delivery and supply chain stability.
  • Customer Service: Responsive and knowledgeable support is crucial for smooth transactions and problem-solving.

Leveraging Chinese Manufacturers for Your Supply Chain
