Quality Control

Our 5-Isopropyl-2-Methoxy-4-Methylbenzenesulfonyl Chloride is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and identity. Certificates of Analysis (COA) detailing all specifications are provided to guarantee traceability and compliance with your R&D or production requirements.

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.
