For companies and researchers involved in the production of advanced biodegradable polymers, such as D-polylactic acid (PLLA), the procurement of high-quality D-lactide is a critical first step. D-Lactide, with its specific CAS number 13076-17-0, is a chiral monomer whose purity and consistency directly influence the final polymer's properties and performance. This guide outlines key considerations for successfully sourcing this vital chemical compound.

When looking to buy D-lactide, it is essential to prioritize suppliers who can guarantee a high level of purity. For most advanced applications, particularly in the medical field, a minimum purity of 99.5% is typically required. Impurities can interfere with the polymerization process, leading to lower molecular weight polymers, inconsistent stereoregularity, or even undesirable side reactions that compromise the final product's integrity and biocompatibility. Therefore, always inquire about the supplier's quality control measures and any available certifications or analytical data.

Understanding the packaging and minimum order quantities is also crucial for efficient procurement. D-lactide is commonly supplied in drums or bags, often in 25kg quantities, suitable for bulk industrial use. For research and development purposes, smaller quantities might be available, but it's important to verify this with potential suppliers. Establishing a reliable supply chain is key, especially for ongoing manufacturing processes, so consider the supplier's production capacity and their ability to meet your projected demand.

Beyond the chemical specifications, consider the supplier's reputation and customer service. A knowledgeable supplier can provide valuable technical support, assist with regulatory compliance, and offer insights into handling and storage best practices for D-lactide. Look for companies that specialize in fine chemicals or polymer precursors, as they are more likely to have the expertise and infrastructure to deliver consistently high-quality products.

When initiating an inquiry for D-lactide (CAS: 13076-17-0), be prepared to provide details about your intended application and the specific quality parameters you require. This will help suppliers offer the most suitable product and pricing. Furthermore, comparing quotes from multiple reputable suppliers can ensure you are getting competitive pricing without compromising on quality. Investing time in finding the right supplier for your D-lactide needs will lay a strong foundation for your product development and manufacturing success.
