Quality Control

Our 3-Buten-2-One, 1,1-Dichloro-3-Methyl- is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity for research and development applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles, typically determined by GC, HPLC, and NMR. We are committed to meeting the stringent requirements of our global R&D and process chemistry clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to the reactive nature of halogenated ketones, it should be stored separately from strong bases and reducing agents.
