Quality Control

Every batch of 2-Butene-1-Thiol, (2E)- is produced and analyzed under strict quality management protocols. We ensure compliance with relevant industry standards through rigorous in-process and final release testing. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and meet your quality assurance requirements.

Storage

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