Quality Control

Our n-[(9,10-Dihydro-4-Hydroxy-9,10-Dioxoanthracen)-1-Yl]-β-Alanine Methyl Ester is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to verify identity and purity. Certificates of Analysis (COA) detailing all specifications are available upon request, supporting compliance with internal and international quality standards.

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 light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from incompatible materials such as strong oxidizing agents.
