Quality Control

Our production of Hydrogen Bis[3,5-Di-tert-Butylsalicylato(2-)-O1,O2]Chromate(1-) adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) documenting purity, physical characteristics, and performance indicators are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after each use to prevent moisture absorption and degradation. Keep away from incompatible materials such as strong acids and strong oxidizing agents.
