Quality Control

Our Isoamyl 3-(Methylthio)Propionate is produced and tested to meet stringent quality standards suitable for flavor and fragrance applications. We ensure compliance with relevant industry guidelines, including FEMA and FCC where applicable. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and organoleptic properties is provided with each batch to guarantee consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (15-25°C). Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening and minimize headspace to preserve quality and prevent degradation.
