Quality Control

Our 4-Bromo-3-Methylphenyl Chlorothioformate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and identity confirmation. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical quality parameters. Our commitment to consistent quality and traceability supports our clients' needs for reliable and reproducible results in their critical synthesis workflows.

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. Keep away from heat, sparks, and open flame.
