Navigating the global chemical market for specialized intermediates like 8-Hydroxyquinoline Sulfate (CAS 134-31-6) can be a complex undertaking for purchasing managers and R&D professionals. China, as a leading global manufacturing hub, offers a vast array of chemical suppliers. This article provides essential insights for businesses looking to source high-quality 8-Hydroxyquinoline Sulfate, focusing on what to look for in a Chinese manufacturer and supplier, from product specifications to supply chain reliability.

Understanding 8-Hydroxyquinoline Sulfate: Properties and Uses

8-Hydroxyquinoline Sulfate is a yellow crystalline powder known for its potent fungicidal, preservative, disinfectant, and metal chelating properties. Its primary applications span across agriculture, industrial processes, and even some pharmaceutical formulations. Key specifications that buyers typically focus on include:

  • Purity: Usually specified as 99% minimum.
  • Appearance: Yellow crystalline powder.
  • CAS Number: 134-31-6.
  • Molecular Formula: C9H7NO.H2O4S (often presented as (C9H7NO)2•H2SO4).
  • Melting Point: Typically in the range of 175.0-178.0ºC.
  • Solubility: Insoluble in water or carbon dioxide.
  • Stability: Stable under ordinary conditions.

These properties make it a critical component in crop protection products, disinfectants, and chemical synthesis requiring metal sequestration.

Key Considerations When Sourcing from China

When you decide to buy 8-Hydroxyquinoline Sulfate from China, several factors are critical for a successful procurement:

  1. Supplier Selection and Verification:
    • Experience: Prioritize suppliers with a proven track record, especially those with over 10 years of export experience. This indicates a deeper understanding of international trade and quality standards.
    • Audited Suppliers: Look for suppliers who have undergone third-party audits, verifying their business licenses and operational capabilities. Platforms often highlight 'Audited Suppliers' or 'Diamond Members.'
    • Reputation: Check for partnerships with Fortune 500 companies or high repeat buyer rates, which signify trust and consistent performance.
  2. Product Quality and Consistency:
    • Certifications: ISO 9001 certification is a good indicator of a robust quality management system.
    • Detailed Specifications: Ensure the supplier provides comprehensive product specifications and a Certificate of Analysis (CoA) for each batch, detailing purity, impurity profiles, and other relevant parameters.
    • Sample Availability: Always request samples to perform your own quality checks and application tests before committing to bulk orders.
  3. Pricing and Commercial Terms:
    • Competitive Pricing: Obtain multiple quotes for your required quantities to ensure you are getting a competitive price. Be mindful of MOQs (Minimum Order Quantities).
    • Payment and Shipping: Clarify payment terms (e.g., T/T, L/C) and shipping arrangements. Understand Incoterms and estimated delivery times.
  4. Production Capacity and Lead Times:
    • Capacity: For large volumes, verify the supplier's monthly production capacity (e.g., 20mts/Month).
    • Reliability: Assess their ability to meet your production schedule and communicate proactively about any potential delays.
  5. Technical Support and Customization:
    • Documentation: Ensure availability of Material Safety Data Sheets (MSDS) and other technical documentation.
    • Customization: If specific modifications or packaging are needed, inquire about their customization capabilities.

    The Value of a Direct Manufacturer Relationship

    Engaging directly with a manufacturer, such as those based in major industrial centers like Shanghai, often provides better insights into the production process, quality control measures, and can lead to more direct communication and potentially better pricing.
