Quality Control

Our 5-n-Octylthiophene-2-Boronic Acid is manufactured under strict quality protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR (¹H, ¹³C, ¹¹B), and mass spectrometry, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specifications and test results. Our quality system is designed to meet the stringent requirements of research and development as well as scale-up production.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its hygroscopic and potentially air/moisture-sensitive nature. Allow the container to reach room temperature before opening to minimize moisture ingress.
