Quality Control

Our 3-Buten-2-One, 4,4-Dimercapto- is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We can support development projects with custom purity grades and analytical method development.

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. Recommended storage temperature is 2-8°C for long-term stability. Due to its easily oxidized nature, minimize exposure to air and moisture during handling.
