Quality Control

Our 2-(4-Chloro-2-Methylphenoxy)Butanoic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications. We support our global clients with documentation relevant to their regional regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
