Quality Control

Our 1-Butyl-4,4-Dimethyl-1-Bora-2,5-Dioxacyclopentan-3-One is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and GC analysis, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

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