Beyond its pharmaceutical significance, 5-Hydroxyanthranilic Acid (CAS 394-31-0) plays a vital role as an intermediate in the dye industry, particularly for azo and sulfur dyes. For professionals in dye formulation and manufacturing, understanding the procurement and application of this fine chemical is key to achieving optimal results. This guide focuses on its use in dye synthesis and how to effectively buy it.

5-Hydroxyanthranilic Acid in Dye Production

5-Hydroxyanthranilic Acid, chemically known as 2-Amino-5-hydroxybenzoic acid, is a valuable intermediate for producing specific types of dyes. Its chemical structure allows it to participate in reactions that form chromophores, giving dyes their color. Its common synonyms and CAS number (394-31-0) are crucial for accurate identification when sourcing. As a manufacturer or supplier, highlighting its suitability for producing azo and sulfur dyes, as well as photosensitive paper, is important for targeting B2B clients in the chemical industry.

Key Considerations for Dye Manufacturers

When looking to purchase 5-Hydroxyanthranilic Acid for dye applications, consider these critical aspects:

  • Color and Purity: The gray-brownish crystalline powder appearance is typical. However, purity is paramount, as impurities can affect dye shade, fastness, and performance. Requesting a detailed specification sheet from the supplier is standard practice.
  • Batch Consistency: For industrial applications, consistent batch-to-batch quality is essential. A reliable manufacturer in China will maintain stringent quality control processes.
  • Competitive Pricing: Obtaining multiple quotes from various suppliers will help secure the best price for your required volumes. Bulk purchasing can lead to significant cost savings.
  • Application-Specific Grades: While general purity is important, inquire if specific grades are available or recommended for particular dye types to optimize synthesis.
  • Lead Times and Logistics: Understand the delivery timelines from your chosen supplier to ensure your production schedule remains on track.

Sourcing Strategies for Bulk Purchases

For dye manufacturers requiring substantial quantities of 5-Hydroxyanthranilic Acid, establishing a relationship with direct manufacturers in China is often the most cost-effective strategy. These companies can offer wholesale pricing and large-scale production capabilities. When contacting potential suppliers, clearly state your requirements for purity, quantity, and delivery timeline. Utilizing online B2B platforms or chemical directories can help identify reputable manufacturers and suppliers. For your dye formulation needs, sourcing 5-Hydroxyanthranilic Acid from established chemical hubs in China ensures a balance of quality and cost-effectiveness.
