Quality Control

Our (S S)-β-Naphthyl-Nas Bromide is manufactured under strict quality control protocols to ensure high chemical and chiral purity, essential for sensitive asymmetric synthesis. Each batch is analyzed using advanced chromatographic and spectroscopic techniques. Certificates of Analysis (COA) detailing purity, enantiomeric excess (ee), and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
