For professionals in the pharmaceutical and chemical research sectors, acquiring high-quality intermediates is a critical step in the synthesis process. (S)-4-Benzyl-3-propionyloxazolidinone (CAS: 101711-78-8) is a prime example of such an essential compound, widely used as a chiral auxiliary and a building block for complex molecules. Navigating the global market to buy this intermediate, especially from China manufacturers, requires a strategic approach focused on quality, price, and supplier reliability. This guide offers expert insights to assist you in making informed purchasing decisions.

Understanding the Value Proposition of (S)-4-Benzyl-3-propionyloxazolidinone

This oxazolidinone derivative is highly prized for its role in asymmetric synthesis, enabling the creation of enantiomerically pure compounds essential for pharmaceuticals and other fine chemicals. Its consistent performance in reactions like aldol additions and alkylations makes it a sought-after intermediate. When you are looking to buy this compound, consider its purity levels (often specified as >95% or >99% HPLC), optical rotation, and stability, as these directly impact the success of your synthetic steps.

Key Considerations When Buying from China Manufacturers

China is a leading global producer of chemical intermediates, offering competitive pricing and extensive manufacturing capacity. To ensure a successful purchase of (S)-4-Benzyl-3-propionyloxazolidinone:

  • Supplier Verification: Research potential manufacturers thoroughly. Look for established companies with a strong online presence, clear contact information, and professional communication. Websites like Alibaba or dedicated chemical sourcing platforms can be starting points, but direct verification is key.
  • Quality Assurance: Always request a Certificate of Analysis (CoA) with your order. This document should detail the product's specifications, including purity, CAS number, and analytical methods used. Verify that the supplier can provide lot-specific CoAs.
  • Price and Minimum Order Quantity (MOQ): Obtain quotes from multiple suppliers to compare pricing. Be aware of their MOQs, which can vary significantly. For R&D quantities, look for suppliers who cater to smaller orders, while scaling up production may require engaging with larger manufacturers.
  • Communication and Service: Responsive and clear communication is vital. A good supplier will readily answer your questions about the product, synthesis methods, and shipping. Consider requesting a sample to assess quality before committing to a large purchase.
  • Logistics and Lead Times: Clarify shipping costs, estimated delivery times, and any import/customs regulations that might apply. Understanding lead times is crucial for project planning.

By adopting a diligent approach to sourcing, you can effectively leverage the strengths of China's chemical manufacturing sector to procure high-quality (S)-4-Benzyl-3-propionyloxazolidinone at competitive prices, thereby enhancing your research and production capabilities.
