Quality Control

Every batch of 16,17-Dimethoxyanthra[9,1,2-cde]benzo[rst]pentaphene-5,10-diyl bis(hydrogen sulphate) is produced and analyzed under strict quality protocols. We employ advanced analytical techniques including HPLC, NMR, and mass spectrometry to ensure identity, purity, and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment. Our quality system is designed to meet the rigorous demands of research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under anhydrous conditions, such as in a desiccator or under an inert atmosphere, to prevent degradation. Keep away from incompatible materials.
