Quality Control

Our research-grade biochemicals are produced and tested under stringent quality management systems. Each batch undergoes comprehensive analytical characterization to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided, typically including data from HPLC, NMR, and MS analysis. We support compliance with relevant GLP and ISO standards for research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This compound is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions or a dry inert atmosphere to prevent decomposition. Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture ingress.
