Quality Control

Our 2-Ethyl-4-Methylpentanal is produced under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including GC, IR, and NMR, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications. We adhere to cGMP principles where applicable to support our customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its easily oxidized nature, minimize headspace in opened containers.
