Quality Control

Our Coumarin 307 is produced under strict quality management protocols to ensure batch-to-batch consistency and high performance. We employ advanced analytical techniques, including HPLC, NMR, and mass spectrometry, to verify identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing purity, fluorescence quantum yield, and spectral data is provided with each shipment to support your R&D and manufacturing requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to prevent degradation. Keep the container sealed in a dry environment to maintain product integrity.
