Quality Control

Every batch of (2R)-2-Ethyl-4-oxopentanal is manufactured under strict quality management systems. Our products undergo rigorous analytical testing, including chiral purity analysis by HPLC, to ensure compliance with exacting R&D and process chemistry standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and chiral excess is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation and degradation. Allow the container to reach room temperature before opening to prevent moisture condensation. Keep away from strong oxidizing agents.
