Quality Control

Our 4-Methoxy-2-Methyl-2-Butanethiol is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including GC, GC-MS, and NMR, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment. We are committed to meeting the exacting standards required for research and industrial synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Due to its highly volatile and easily oxidized nature, the container should be kept tightly sealed and away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C for long-term stability.
