Quality Control

We maintain a rigorous quality management system to ensure batch-to-batch consistency and high purity. Our products undergo comprehensive analytical testing, including HPLC, NMR, and mass spectrometry, to verify identity and purity. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment. Our manufacturing and quality processes support development under cGMP guidelines for pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This compound is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive); therefore, containers should be kept sealed under an inert atmosphere if necessary.
