Quality Control

Every batch of 3-Benzofurancarboxaldehyde, 5-Methyl- (9Ci) is produced and tested under strict quality management protocols to ensure consistency and purity for research and industrial use. Our products undergo rigorous quality testing, including chromatographic purity analysis and identity confirmation. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle and store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after opening the original container. Keep away from incompatible materials.
