Quality Control

Our Trt-Cys(Trt)-Osu Benzene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for sensitive synthetic applications. Certificates of Analysis (COA) with detailed specifications are provided for every shipment to guarantee reproducible performance and supply chain reliability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive); allow the sealed container to equilibrate to room temperature before opening to prevent condensation. Keep under inert atmosphere (argon or nitrogen) for optimal shelf life.
