Quality Control

Our (E)-4-(3-Methylphenyl)But-3-En-2-One is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, GC for residual solvents, and spectroscopic methods (IR, NMR) for structural confirmation, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be opaque or stored in dark conditions.
