Quality Control

Our 1-Chloro-3-Pentanone is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP and ISO standards for industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile and light-sensitive nature, we recommend storage at controlled room temperature (15-25°C). Keep container tightly sealed when not in use to prevent evaporation and moisture absorption.
