Quality Control

Every batch of 5-Cyano-2,3-Di-(p-Tolyl)Tetrazolium Bromide is manufactured under strict quality management protocols. We guarantee high chemical purity and consistency, supported by comprehensive analytical testing including HPLC, NMR, and mass spectrometry. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to ensure compliance with your research and production standards.

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 in a dry environment to prevent degradation. Keep away from incompatible materials.
