Quality Control

Our 5-Bromo-2-Methyl-2H-Isoindole-1-Sulfonic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy, to ensure it meets the high standards required for research and commercial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, guaranteeing traceability, consistency, and compliance with your specifications.

Storage

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