For chemical industry professionals, the process of sourcing raw materials like Diethyl Fumarate (CAS 623-91-6) demands diligence. Whether you are involved in complex organic synthesis or polymer production, ensuring the quality and reliability of your chemical inputs is non-negotiable. This guide aims to help procurement managers and R&D scientists understand how to effectively buy Diethyl Fumarate by focusing on key considerations when selecting a manufacturer or supplier.

Understanding the Product: Diethyl Fumarate Essentials

Diethyl Fumarate is a clear, colorless liquid with a molecular formula of C8H12O4 and CAS number 623-91-6. Its primary role is as an intermediate in organic synthesis, notably in the production of pharmaceuticals like neurokinin-1 receptor antagonists, and as a comonomer in polymer manufacturing, such as polystyrene. The typical purity offered by reputable suppliers is 99.5% minimum, a critical specification for many advanced applications.

Key Factors When Selecting a Supplier

When you search for a Diethyl Fumarate manufacturer or supplier, consider these crucial aspects:

  • Quality Verification: Always request a Certificate of Analysis (CoA) for each batch. This document details the product’s purity, physical properties, and any detected impurities. A reliable supplier will readily provide this information.
  • Manufacturing Standards: Inquire about the supplier's manufacturing processes and quality control systems. ISO certifications or adherence to GMP (Good Manufacturing Practices) where applicable, indicate a commitment to quality.
  • Supply Chain Reliability: For industrial users, consistent availability is vital. Look for suppliers with established production capacities and robust logistics to ensure timely delivery, especially for bulk orders in 200kg drums.
  • Technical Support: A good supplier offers technical assistance, helping you understand product handling, storage, and application best practices.
  • Transparent Pricing: While price is a factor, prioritize value. Competitive pricing from a trusted Chinese manufacturer can offer significant cost benefits without compromising quality.

The Purchase Process: From Inquiry to Delivery

To effectively buy Diethyl Fumarate, initiate contact with potential suppliers by clearly stating your requirements: product name, CAS number, desired purity, quantity, and delivery timeline. Requesting samples for preliminary testing is also a wise practice. A professional supplier will respond promptly with a detailed quote and relevant product documentation.
