Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for research and pharmaceutical development. Each batch is characterized using advanced analytical techniques including NMR, HPLC, and mass spectrometry to confirm identity, purity, and consistency. Certificates of Analysis (COA) detailing all critical quality attributes are available upon request, supporting your regulatory and quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) in a dry, cool environment. This compound is hygroscopic (moisture-sensitive) and light-sensitive. Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture condensation.
