Quality Control

Our Dl-2-Methylbutyryl Chloride is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay and impurity profile determination by GC and/or HPLC, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and reacts violently with water, strong bases, and alcohols. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent degradation from moisture and ensure maximum shelf life.
