Quality Control

Our Butanoyl Chloride, 2,3-Dimethyl- is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including GC/HPLC for purity and identity confirmation, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles 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 away from heat and incompatible materials. Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Recommended storage temperature is 2-8°C for long-term stability.
