Quality Control

Our Coumarin-340 is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity, spectroscopic identification, and impurity profiling. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). For long-term storage, consider sealing under an inert gas such as nitrogen or argon.
