Quality Control

Our 1-((3-(3-Chloro-4-Fluorophenyl)Propyl)Dimethylsilanyl)-4-Ethoxybenzene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for advanced synthetic applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

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