Quality Control

Our 5-Pyridin-4-Ylthiophene-2-Carboxaldehyde 97% is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy, to ensure it meets the specified 97% minimum purity. Certificates of Analysis (COA) detailing all test results are provided and 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, and well-ventilated place 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.
