Quality Control

Our Potassium (4-Carboxyphenyl)Trifluoroborate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each 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 room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect product stability and performance.
