Quality Control

Our Bis(3-Carboxyphenyl)(3-Trifluoromethylphenyl)Phosphine is manufactured under strict quality protocols. Each batch undergoes rigorous analytical testing, including HPLC and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle and store the material under an inert atmosphere such as nitrogen or argon for long-term stability. Keep away from strong acids and incompatible materials.
