Quality Control

Our 4,4,5,5-Tetramethyl-2-(4-Methylnaphthalen-1-Yl)-1,3,2-Dioxaborolane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including NMR and HPLC, to ensure high chemical purity and lot-to-lot consistency suitable for demanding synthetic applications. Certificates of Analysis (COA) with detailed specifications are provided to guarantee compliance with your research or production requirements.

Storage

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