Quality Control

Every batch of 4-Cyanophenethyl 4-Methylbenzenesulfonate is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity standards required for sensitive synthetic applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is available for each lot upon request.

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 each use to prevent degradation from atmospheric moisture.
