As a procurement manager or research scientist in the chemical industry, sourcing high-quality raw materials is paramount. One such critical compound is 3-Nitrophthalhydrazide (CAS 3682-15-3), a vital organic synthesis intermediate. If you are looking to buy this chemical, understanding the nuances of procurement, especially from international suppliers like those in China, is essential. This article serves as a practical guide for purchasing 3-Nitrophthalhydrazide, focusing on key considerations for B2B buyers.

Understanding 3-Nitrophthalhydrazide
3-Nitrophthalhydrazide, with the CAS number 3682-15-3, is an organic compound characterized by its nitro group and phthalhydrazide structure. Its molecular formula is C8H5N3O4, and it typically presents as a light yellow to dark green powder or crystalline solid. A significant property is its high melting point, often exceeding 300°C, which suggests good thermal stability. It is primarily used as an intermediate in organic synthesis, acting as a crucial building block for more complex molecules used in various chemical applications.

Key Considerations for Buyers
When you intend to purchase 3-Nitrophthalhydrazide, several factors should be at the forefront of your mind:

  1. Purity and Quality: For organic synthesis, purity is critical. Look for suppliers who provide detailed Certificates of Analysis (COA) stating the purity, often specified as ≥97% or ≥98%. Reputable manufacturers will offer consistent quality across batches.
  2. Supplier Reliability: Identifying a reliable manufacturer or supplier is key to ensuring a steady supply chain. China has a robust chemical manufacturing sector, offering numerous options. It's advisable to work with established companies that have a proven track record and good customer service.
  3. Pricing and Quotation: The price of 3-Nitrophthalhydrazide can vary based on quantity, purity, and supplier. Always request a formal quote, especially for bulk orders. Comparing prices from different manufacturers will help you secure the best value. Factors influencing price include production costs, raw material availability, and market demand.
  4. Packaging and Shipping: Ensure the supplier can package the material appropriately for safe transit and storage. Common packaging includes drums or bags, often customized to customer needs. Understand the shipping terms and estimated delivery times.
  5. Technical Support and Documentation: A good supplier will offer comprehensive documentation, including Material Safety Data Sheets (MSDS) and technical specifications. Some may also provide application support or insights into synthesis methods.

Navigating the Chinese Market
When sourcing 3-Nitrophthalhydrazide from China, engage with suppliers who clearly list their product details, CAS numbers, and quality specifications. Many Chinese chemical manufacturers are experienced in international trade and can cater to global B2B clients. Look for suppliers who actively communicate and are transparent about their production processes and quality control measures.

In conclusion, if you are in the market to buy 3-Nitrophthalhydrazide, focusing on purity, supplier reliability, competitive pricing, and comprehensive documentation will lead you to a successful procurement. Engaging with experienced manufacturers and suppliers in China can provide access to high-quality organic synthesis intermediates at competitive prices, supporting your research and production goals.
