Quality Control

Our Potassium (5-Bromo-2-Thienyl)Acetate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) in a desiccator for long-term preservation. Recommended storage temperature is 2-8°C.
