Quality Control

Every batch of Azalein is produced and tested under strict quality management protocols to ensure identity, purity, and consistency. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing key parameters such as assay, related substances, and residual solvents as applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). This material is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed in a low-humidity environment.
