Quality Control

Our Potassium (4-Methylphenylsulfonamido)Methyltrifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for every lot 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). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) in its original packaging to prevent degradation. Keep away from incompatible materials.
