Quality Control

Our Methyl 3-(Phenylthio)Isobutyrate is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key specifications 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). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); therefore, containers should be kept tightly sealed under an inert gas blanket after opening to maintain product integrity.
