Quality Control

Every batch of α-(Methylsulfonyl)Cyclopentenepropanoic Acid Methyl Ester is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the compound meets the exacting standards required for research and development. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles by HPLC, GC, and NMR is supplied with each shipment to guarantee traceability and consistency 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 (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which may affect stability and performance. Keep away from incompatible materials such as strong oxidizing agents.
