Quality Control

We maintain a strict quality management system to ensure batch-to-batch consistency and high purity for research and development applications. Our products undergo rigorous quality testing, including HPLC, GC, and NMR analysis, to verify identity, purity, and isomeric composition. Certificates of Analysis (COA) detailing all specifications and test results are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. For long-term storage, consider storing under an inert atmosphere to maintain optimal stability.
