Quality Control

Our Butyldichlorophosphine is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, identity, and impurity profile. We adhere to relevant industry standards and can provide material tailored to specific research or production requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product must be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Recommended long-term storage temperature is 2-8°C. Keep away from moisture, strong bases, and oxidizing agents.
