Quality Control

Our [4-(Trimethylsiloxy)Phenyl]Propenoic Acid Methyl Ester is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistent performance. 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 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.
