Quality Control

Our Rhodamine B Amine is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and moisture content. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your research or production specifications.

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 tightly sealed after opening to prevent degradation from atmospheric moisture.
