Quality Control

Our 3,4-Epithiobutanenitrile is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation. A Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment to guarantee compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its highly volatile nature, keep away from heat, sparks, and open flame. Containers should be kept tightly sealed when not in use to prevent evaporation and moisture ingress.
