Quality Control

Our (1R-Trans)-3-(2,2-Dichlorovinyl)-2,2-Dimethylcyclopropanecarbonyl Chloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high chemical purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, enantiomeric excess, and impurity profiles. We adhere to relevant industry standards to meet the stringent requirements of our global B2B clientele in regulated markets.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen) after opening. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong acids and incompatible organic solvents.
