Quality Control

Our 3-(2-Ethyl-Phenyl)-Acrylic Acid undergoes rigorous quality testing to ensure compliance with industry standards. We maintain strict in-process controls and final product verification. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area 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.
