Quality Control

Every batch of (1-Butenyl-1)Methylsulphide is produced and tested under a strict quality management system to ensure consistency and reliability for industrial and research applications. Our products undergo rigorous quality testing, including chromatographic purity analysis and identity confirmation, to ensure compliance with industry standards. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Keep away from strong oxidizing agents, strong acids, and strong bases. Due to the potential for oxidation and sensitivity, handling under an inert atmosphere (e.g., nitrogen) is recommended for long-term storage or after opening.
