Quality Control

Our trans-3-(4-Methoxyphenyl)-Acryloyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) with detailed specifications are provided to guarantee consistency and traceability for your critical applications.

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 and reactivity as a strong acid/organic solvent derivative, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from heat, open flames, and incompatible materials such as bases, alcohols, and amines.
