Quality Control

Our (2-Sulfanylphenyl)Boronic Acid is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for every shipment 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 a 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.
