For procurement specialists in the chemical and pharmaceutical sectors, efficiently sourcing critical raw materials like L-Glutamic acid 5-methyl ester (CAS 1499-55-4) is a continuous challenge. This amino acid derivative is not just another chemical; it's a vital intermediate that underpins research, development, and manufacturing processes. This guide aims to equip procurement managers with the knowledge to effectively buy this essential compound.

Key Information for Procurement: L-Glutamic Acid 5-Methyl Ester

Before initiating a purchase, understanding the core details of L-Glutamic acid 5-methyl ester is crucial. Known by its CAS number 1499-55-4, it has a molecular formula of C6H11NO4 and a molecular weight of 161.16. Typically, it is supplied as a white amorphous powder with high purity, often exceeding 99%. Its primary applications are as a pharmaceutical intermediate and a fine chemical reagent, making its quality and consistency paramount.

Strategic Sourcing Considerations:

• Supplier Qualification: When you decide to buy L-Glutamic acid 5-methyl ester, prioritize suppliers who are direct manufacturers. Manufacturers, especially those based in China, often provide more competitive pricing and direct quality control. Look for suppliers with established quality management systems (e.g., ISO certification) and a proven track record.
• Purity and Specifications: Always request a Certificate of Analysis (COA) for each batch. Verify that the purity (≥99%) and other specifications, such as appearance and optical rotation, meet your project's requirements. For pharmaceutical applications, detailed impurity profiles are essential.
• Pricing and Volume: Obtain quotations for different volumes, from laboratory scale (grams) to industrial scale (kilograms or tons). Manufacturers often offer tiered pricing based on order quantity, providing cost savings for larger commitments. Negotiate terms that align with your budget and project timelines.
• Lead Times and Logistics: Understand the supplier's production lead times and shipping options. Reliable logistics are critical to avoid delays in your R&D or manufacturing schedules. For international procurement, consider shipping ports like Shanghai or Qingdao for efficient global distribution.
• Technical Support: A good supplier will offer technical assistance regarding product handling, storage, and application. This support can be invaluable for optimizing your processes.
