Quality Control

Our (E)-3-(1-Ethyl-5-Methyl-1H-Pyrazol-4-Yl)-Acrylic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for research and production use. Certificates of Analysis (COA) detailing batch-specific results are available upon request, providing full traceability and quality assurance.

Storage

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