Quality Control

Our 2-Butenoic Acid, 4-Amino-, Methyl Ester, Hydrochloride (1:1), (2E)- is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing specific batch results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
