BP10955 D-Lactide (D-LA) Powder CAS: 13076-19-2

D-Lactide (D-LA) Powder CAS: 13076-19-2 Description

D-Lactide (D-LA) Powder, chemically recognised as the cyclic dimer of D-lactic acid, serves as a monomer for synthesising polylactic acid (PLA) via ring-opening polymerisation. Its chiral purity supports controlled degradation rates and enhances polymer mechanical properties. The formulation enables precise control over molecular weight and thermal properties, which is critical for applications in biomedical and industrial settings. Detailed compositional analysis and in-house quality assessments ensure consistency and performance across batches.

D-Lactide (D-LA) Powder CAS: 13076-19-2 Packing

The powder is packaged in a double-layer vacuum-sealed bag, featuring an inner PE layer and an outer aluminium-plastic composite layer, which effectively prevents contamination and moisture ingress. It is recommended to store the product in a cool, dry environment with stable temperature to maintain its chemical integrity. This packaging structure is specifically designed to ensure the stability of the powder during transportation and storage. Please note that caking within the vacuum-sealed packaging is a normal occurrence. If the packaging remains intact, the product can be safely pulverised back into a powder for use. Custom packaging sizes and bulk packaging options are available upon request.

Storage and Handling Instructions

To maintain the stability and intended properties of D-LA, please strictly adhere to the following storage and handling guidelines:

Storage Conditions

Store in a cool, dry, and dark place.

Short-term storage (up to several days): May be kept at room temperature in a dry environment.

Long-term storage: Must be frozen at -20°C to minimise degradation.

Moisture & Degradation Prevention

Avoid contact with substances that can trigger degradation, including water, acids, alkalis, alcohols, and amines.

Maintain relative humidity below 30% and temperature below 25°C in both operational and storage environments.

Handling Procedure

When removing the product from frozen storage, keep the container sealed and allow it to reach room temperature before opening. This prevents atmospheric moisture from condensing onto the cold product, which could initiate degradation.

Additional Information

D-Lactide is the optically active cyclic dimer of lactic acid, serving as a stereospecific precursor for the synthesis of poly(D-lactic acid) (PDLA). Its controlled polymerisation behaviour allows for precise tuning of crystallinity and degradation kinetics, making it particularly suitable for applications that demand predictable mechanical stability and controlled resorption. Researchers value D-LA for its consistent stereochemical purity and reproducible polymerisation performance under controlled processing conditions.

Advanced studies in polymer science continue to explore the role of D-lactide in designing stereocomplex PLA materials with enhanced thermal and mechanical properties. Understanding its crystallisation behaviour, thermal stability, and hydrolytic degradation profile is essential for optimising processing parameters and ensuring reliable performance in biomedical implants, controlled-release systems, and high-performance biodegradable packaging.
