Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. For this advanced intermediate, quality is assured through multiple orthogonal analytical techniques including HPLC, chiral analysis, and NMR spectroscopy to confirm identity, purity, and enantiomeric excess, meeting the stringent requirements of research and development applications.

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); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation or clumping. For long-term storage, consider using desiccants.
