Quality Control

Our 1-Ethyl-1H-Indole-4-Carbaldehyde is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with full traceability are provided and available upon request, supporting compliance with research and cGMP (current Good Manufacturing Practice) standards where applicable.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
