Quality Control

Our Ethyl 2-Methyl-2-(Methylthio)Propionate is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including GC/HPLC for assay and purity and spectroscopic identification (IR, NMR), to ensure it meets precise customer specifications. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed-upon standards.

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 easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from heat, sparks, and open flame.
