Quality Control

Our 2-Naphthalenecarboxaldehyde, 4A,8A-Dihydro- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and structural confirmation, to ensure consistency and reliability for research applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay purity and identity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its sensitivity to oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
