Quality Control

Our 2-[2-(4-Pentylphenyl)Vinyl]-4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical characterization, including NMR, HPLC, and GC analysis, to confirm identity, purity, and the absence of critical impurities. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all relevant specifications. We support compliance with REACH and other global regulatory frameworks as required.

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 product is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
