Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We employ advanced analytical techniques including HPLC, GC, and NMR to verify identity, purity, and chiral integrity. Certificates of Analysis (COA) are available upon request, detailing batch-specific results for all critical parameters. Our quality management system is designed to support cGMP and ISO standards for reliable, reproducible supply to demanding R&D and scale-up environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. For long-term stability, storage at 2-8°C is recommended. Keep away from heat, sparks, and open flame. The container should be kept tightly sealed in a dry environment to minimize exposure to moisture.
