For procurement managers in the pharmaceutical and fine chemical industries, sourcing critical intermediates like 1,2-Cyclohexanedicarboximide (CAS: 7506-66-3) is a cornerstone of efficient production and research. Understanding the market, key specifications, and reliable suppliers is paramount. This guide aims to equip you with the essential knowledge to effectively source this vital compound.

Understanding 1,2-Cyclohexanedicarboximide

1,2-Cyclohexanedicarboximide, also known by its synonym cis-Hexahydro-1H-isoindole-1,3(2H)-dione, is primarily recognized for its role as an intermediate in the synthesis of Perospirone, an important antipsychotic drug. Its chemical formula is C8H11NO2, with a molecular weight of 153.178. Key physical properties include a density of 1.18 and a boiling point of 330.8ºC, with a flash point of 159.3ºC. For practical industrial use, its appearance as a white crystalline powder and a purity assay of ≥98.0% are standard, alongside a low loss on drying (≤1.0%), ensuring consistency and quality in downstream applications.

Why China is a Key Sourcing Hub

China has emerged as a global powerhouse for chemical manufacturing, offering a vast array of intermediates at competitive prices. When you look to buy 1,2-Cyclohexanedicarboximide, China-based manufacturers and suppliers are often the first point of inquiry for procurement professionals due to their production scale and cost-effectiveness. For instance, many suppliers offer the product packaged in 25 kg drums, with options for custom packaging to meet specific client requirements. Identifying a reliable manufacturer is key to ensuring not just price, but also consistent quality and timely delivery.

Key Considerations for Procurement

When evaluating suppliers for 1,2-Cyclohexanedicarboximide, several factors are critical for procurement managers:

  • Purity and Specifications: Always confirm that the product meets your required assay (typically ≥98.0%) and other critical specifications like loss on drying.
  • Supplier Reputation and Certifications: Look for suppliers with established quality management systems (e.g., ISO certifications) and a proven track record in the industry.
  • Pricing and Minimum Order Quantity (MOQ): Obtain quotes for bulk purchases to understand the price per kilogram and any applicable discounts. Clarify the MOQ to ensure it aligns with your project needs.
  • Lead Times and Logistics: Understand the production lead time and shipping options from China to your destination. Efficient logistics are crucial for maintaining production schedules.
  • Technical Support: A good supplier should be able to provide technical data sheets (TDS), Certificates of Analysis (CoA), and potentially even application support.

Finding Your Ideal Supplier

When searching for a supplier of 1,2-Cyclohexanedicarboximide, using terms like '1,2-Cyclohexanedicarboximide manufacturer China' or 'buy cis-Hexahydro-1H-isoindole-1,3(2H)-dione price' can yield relevant results. Many chemical directories and B2B platforms list reputable companies. For example, companies specializing in pharmaceutical intermediates often stock this compound. Engaging with multiple suppliers to compare offerings is a standard procurement practice. Prioritize suppliers who demonstrate transparency regarding their production processes and quality control measures. This due diligence ensures that you secure a reliable source for this essential chemical intermediate, supporting the successful development and manufacturing of pharmaceuticals.

By focusing on these aspects, procurement managers can confidently identify and engage with top manufacturers and suppliers in China for 1,2-Cyclohexanedicarboximide, securing a stable supply of this critical compound at competitive prices.
