For procurement managers in the agrochemical sector, the acquisition of key intermediates like 1,5-Naphthalene Diisocyanate (NDI, CAS 3173-72-6) requires a strategic approach. Ensuring a consistent supply of high-quality NDI at a competitive price is vital for maintaining production schedules and controlling costs. This guide outlines the essential considerations when looking to purchase this critical chemical from manufacturers and suppliers.

The first step in buying 1,5-Naphthalene Diisocyanate is to identify reputable suppliers. Look for manufacturers who can clearly state their product specifications, particularly the assay (e.g., 99% min), and offer certifications. Companies based in China, such as NINGBO INNO PHARMCHEM CO.,LTD., are significant global producers of NDI. When you search for '1,5-Naphthalene diisocyanate manufacturer China,' you will find options for direct sourcing. It is advisable to work with suppliers who have a proven track record and positive customer reviews regarding product consistency and reliability.

Understanding pricing is another crucial aspect. The price of 1,5-Naphthalene Diisocyanate can vary based on order volume, purity, and market conditions. Initiating a price inquiry for bulk purchases is the most effective way to obtain accurate quotes. Many suppliers offer online purchase support, allowing you to request a quote or place an order directly through their website. When comparing prices, ensure you are comparing like-for-like specifications. Factors like packaging (e.g., 25kg/drum) and delivery terms also influence the overall cost.

Quality assurance is non-negotiable when procuring NDI for agrochemical applications. The product's physical form (white to light yellow crystalline powder) and chemical purity directly impact its performance in pesticide formulations. Always request a Certificate of Analysis (CoA) for your order. A reliable supplier will readily provide this documentation, confirming the product meets the required standards. By thoroughly vetting your potential suppliers and understanding the product’s specifications, you can confidently purchase 1,5-Naphthalene Diisocyanate and ensure the success of your agrochemical products.
