Quality Control

Our production of 3-Methyl-2-Buten-2-Ylboronic adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including NMR (¹H, ¹¹B, ¹³C), HPLC, and Karl Fischer titration, to confirm identity, potency, and impurity profiles. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We operate in compliance with cGMP principles where applicable, supporting our commitment to supply reliability for critical R&D and scale-up processes.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (argon or nitrogen) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
