Quality Control

Our 1-(Phenylsulfonyl)-1H-Indole-2-Carbonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high purity and consistency. Certificates of Analysis (COA) with detailed specifications are provided for every shipment to guarantee compliance with your research and production requirements.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
