At NINGBO INNO PHARMCHEM CO.,LTD., we understand that the performance of our chemical intermediates is directly linked to their quality and purity. For D-Lactide (CAS 13076-17-0), maintaining its pristine condition is paramount, especially for its use as a polymerization monomer. This article outlines the essential storage requirements to preserve the integrity of D-Lactide.

D-Lactide, supplied as white crystals with a purity of ≥99.5%, is susceptible to degradation if not stored correctly. The primary culprit for degradation is moisture. Exposure to water can initiate hydrolysis, leading to the breakdown of the lactide ring and compromising its ability to form high-quality polymers like PLLA. Therefore, stringent measures must be taken to keep D-Lactide dry.

Key recommendations for the low temperature storage for D-Lactide include:

  • Sealed Containers: Always store D-Lactide in tightly sealed containers to prevent the ingress of moisture and air. For remaining product after opening, ensure it is re-sealed effectively, avoiding simple ziplock bags which may not provide an adequate seal.
  • Dry Environment: The storage area should be consistently dry, with humidity levels ideally below 35% during handling.
  • Low Temperature: Freezing at -20 degrees Celsius is the recommended storage condition. This significantly slows down any potential degradation processes.
  • Controlled Handling: When removing D-Lactide from cold storage, allow it to reach room temperature *before* opening the container. This prevents condensation from forming on the product's surface, which can lead to degradation. Wipe off any condensation on the bag's exterior before opening.

Adhering to these guidelines is crucial for anyone looking to buy D-lactide for applications requiring precise polymerization. The quality of the D-lactide polymerization monomer directly impacts the properties of the resulting polymers, such as PLLA orthopedic bone screws or other advanced biodegradable materials.

For manufacturers and researchers, the shelf-life and performance consistency of D-Lactide are critical factors. Understanding these storage protocols ensures that the investment in high purity D-Lactide yields the expected results. NINGBO INNO PHARMCHEM CO.,LTD. provides D-Lactide that meets rigorous quality standards, and by following these storage recommendations, users can maximize its potential.

By paying close attention to these storage requirements, customers can ensure that their D-Lactide remains in optimal condition, ready for successful use in polymerization and other critical applications.
