Quality Control

Our production of 4-Diazo-n-Ethyl-n-(2-Hydroxyethyl)Aniline Chloride Zinc Chloride adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including photochemical activity and purity. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles 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 (moisture-sensitive) nature, the container must be kept sealed under dry conditions to prevent decomposition. Keep away from heat and incompatible materials.
