Quality Control

Our 1H-Imidazolium tetrafluoroborate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chiral HPLC for enantiomeric excess (ee) and NMR for structural confirmation, to ensure high purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing purity, chiral purity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) when prolonged exposure is anticipated to maintain stability and performance.
