Quality Control

Every batch of 1,4-Bis(Dicyclohexylphosphonium)Butane Bis(Tetrafluoroborate) is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemicals and advanced intermediates. 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 to guarantee it meets your specified requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation. Keep away from incompatible materials.
