For purchasing managers tasked with sourcing critical chemical intermediates, the selection process demands meticulous attention to quality, cost, and supply chain reliability. 3-Amino-4-hydroxybenzoic Acid (CAS 1571-72-8) is one such compound, vital for industries ranging from dyes to specialty paper. This guide aims to equip procurement professionals with the knowledge to effectively source this essential chemical from leading manufacturers.

Key Considerations for Purchasing Managers

When evaluating potential suppliers for 3-Amino-4-hydroxybenzoic Acid, several factors are paramount:

  1. Product Quality and Specifications: The stated assay of ≥98.0% and the appearance as a white to off-white crystalline powder are baseline requirements. Purchasing managers must verify that the supplier's quality control systems are robust. Certificates of Analysis (CoA) should be readily available upon request.
  2. Supplier Reliability and Experience: Look for manufacturers with a proven track record and significant experience in producing fine chemicals. Companies based in China, such as NINGBO INNO PHARMCHEM CO.,LTD., often provide competitive advantages due to scale and manufacturing expertise.
  3. Pricing and Cost-Effectiveness: While quality is non-negotiable, competitive pricing is a key procurement driver. Obtaining multiple quotes for bulk quantities (e.g., 25kg drums) is a standard practice. Understanding the minimum order quantity (e.g., 1kg) is also crucial for initial evaluation and trial orders.
  4. Supply Chain and Logistics: A stable and efficient supply chain is essential to avoid production disruptions. Enquire about the supplier's production capacity, inventory management, and shipping capabilities to ensure timely delivery to your facility.
  5. Technical Support: Access to technical expertise from the manufacturer can facilitate smoother integration of the chemical into your processes. This includes information on handling, storage, and potential application challenges.

Applications Driving Demand

The consistent demand for 3-Amino-4-hydroxybenzoic Acid stems from its critical role as an intermediate in:

  • Dye Manufacturing: It is a foundational component for producing azo and sulfur dyes, essential for the textile industry.
  • Photosensitive Paper Production: Its chemical properties are integral to the functionality of photosensitive materials used in imaging and printing.
  • Organic Synthesis: It serves as a versatile building block for R&D and the creation of novel compounds.

Making the Purchase Decision

When ready to buy 3-Amino-4-hydroxybenzoic Acid, purchasing managers should reach out directly to manufacturers. Initiating an inquiry via email (e.g., to [email protected]) is typically the first step. Clearly state your required quantity, purity needs, and delivery location to receive an accurate quotation. For companies seeking to establish a long-term partnership, evaluating the supplier's overall commitment to quality, service, and innovation is just as important as the initial price.

By following these guidelines, purchasing professionals can confidently source high-quality 3-Amino-4-hydroxybenzoic Acid, ensuring the integrity and efficiency of their manufacturing processes.
