Quality Control

Our production of this specialty fluorochemical adheres to stringent quality protocols to ensure batch-to-batch consistency and purity. Each lot is characterized using advanced analytical techniques including NMR (19F, 1H), FT-IR, and GC-MS/HPLC to confirm identity and assay purity. Comprehensive Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; ensure the container is kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from heat, sparks, and open flame.
