Quality Control

Our 4-Isothiazol-5-Yl-Phenylamine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and GC-MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request, supporting your regulatory and R&D documentation needs.

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 tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
