Quality Control

Our Terephthalic Acid, (Cyanoamino)- (7Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay, impurity profile, and physical characteristics is provided with every shipment to guarantee it meets your research and development requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept in a cool, dry place with minimal humidity fluctuation. Recommended storage temperature is 2-8°C for long-term stability. Ensure the storage area is well-ventilated and separate from incompatible materials.
