Quality Control

Our Mesitylene Sulfonyltetrazole is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and purity, and is supplied with a corresponding Certificate of Analysis (COA). We adhere to relevant industry standards, and our quality systems support the needs of cGMP-compliant pharmaceutical manufacturing.

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 after opening to prevent degradation from atmospheric moisture.
