Quality Control

Our Chlorobutanol is manufactured and tested under a strict quality management system to ensure it meets the rigorous standards required for pharmaceutical and cosmetic applications. We offer grades compliant with relevant pharmacopoeial monographs (e.g., USP, BP, EP). Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles, available upon request to support your regulatory and quality assurance needs.

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, which can affect product quality and stability.
