Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized using advanced analytical techniques to confirm identity, purity, and enantiomeric excess. Certificates of Analysis (COA) are available upon request, detailing specifications such as assay, chiral purity, and impurity profiles. We adhere to a cGMP-compliant quality management system suitable for pharmaceutical development work.

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 specified. Keep away from strong acids, bases, and oxidizing agents.
