Quality Control

Every batch of S-(Trifluoromethyl)Dibenzothiophenium Tetrafluoroborate is manufactured and tested under strict quality management protocols. We ensure compliance with relevant industry standards for high-purity fine chemicals. Comprehensive analytical testing, including NMR, HPLC, and elemental analysis, is performed to verify identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment.

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., argon or nitrogen) for long-term storage to maintain optimal purity and reactivity.
