Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We provide Certificates of Analysis (COA) for every batch, detailing purity and identity confirmation. Quality is assured through analytical techniques including HPLC, NMR, and IR spectroscopy. For custom synthesis or specific purity requirements (e.g., >98%), please contact our technical team to discuss your project specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
