Quality Control

Our Benzenediazohydroxide, p-Carboxy-, Ethyl Ester (7Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its light-sensitive nature, containers should be kept in opaque packaging or amber glass. Keep away from heat, sparks, and open flame. For long-term storage, consider inert atmosphere conditions to maximize stability.
