Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We employ advanced analytical techniques including HPLC, NMR, and MS to verify identity, purity, and consistency. Certificates of Analysis (COA) are available upon request, detailing batch-specific results. Our quality management system is designed to support cGMP-compliant applications where required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a dry environment and away from direct light exposure to maintain stability and purity.
