For procurement managers in the chemical and pharmaceutical industries, securing a reliable supply of high-quality raw materials is paramount. Diethyl 1,2-cyclopentanedicarboxylate (CAS 90474-13-8) is one such compound, increasingly sought after for its utility as a key intermediate in organic synthesis and pharmaceutical manufacturing. Understanding where and how to buy this critical chemical can significantly impact project timelines and budget adherence. This guide aims to provide procurement professionals with essential insights into sourcing this valuable compound effectively.

Understanding the Product: Diethyl 1,2-cyclopentanedicarboxylate
This diester of cyclopentane-1,2-dicarboxylic acid is characterized by its chemical structure, which lends itself to a variety of complex reactions. Its purity, often specified as ≥99%, is a critical factor for its intended applications, particularly in the synthesis of pharmaceutical intermediates. When evaluating suppliers, it is essential to look for manufacturers that adhere to stringent quality control measures, such as GMP or SGS certifications, and meet recognized standards like USP, BP, or EP where applicable.

Key Considerations for Procurement: Purity, Price, and Supply Chain Stability
When seeking to buy Diethyl 1,2-cyclopentanedicarboxylate, procurement managers should prioritize suppliers that can guarantee consistent purity and assay levels. Manufacturers based in China are often a primary source for competitive pricing, but due diligence is crucial. Investigating a supplier's manufacturing capabilities, quality management systems, and historical performance is key. Furthermore, the stability of the supply chain cannot be overstated. Identifying a manufacturer with robust production capacity and reliable logistics ensures that your projects are not hampered by material shortages or delays.

Navigating Synthesis Routes and Manufacturer Specialization
Several synthetic routes exist for Diethyl 1,2-cyclopentanedicarboxylate, including catalytic hydrogenation of oxo-cyclopentanedicarboxylates and modifications of classical methods like Perkin's. A competent manufacturer will not only employ efficient synthesis but also provide detailed technical data sheets (TDS) and safety data sheets (SDS). When making a purchase, consider a supplier that demonstrates expertise in producing this specific intermediate, as this often translates to better product quality and more responsive technical support. For procurement managers looking to purchase in bulk, negotiating directly with the manufacturer can unlock significant cost savings and ensure a tailored supply agreement.

Inquiry and Purchase Process: Securing Your Supply
The process of obtaining Diethyl 1,2-cyclopentanedicarboxylate typically begins with a price inquiry. Reputable suppliers, such as NINGBO INNO PHARMCHEM CO.,LTD., welcome such inquiries and will provide detailed quotations outlining product specifications, pricing per unit or volume, and lead times. When you are ready to buy, be prepared to confirm your order details, including quantity, desired packaging, and delivery location. Establishing a strong relationship with a reliable manufacturer is a strategic move that supports your company's research and development efforts and ensures seamless production runs. By focusing on these key aspects, procurement professionals can confidently source Diethyl 1,2-cyclopentanedicarboxylate and contribute to the successful development of innovative products.
