Quality Control

Our 4-Hydroxybutyraldehyde is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by GC/HPLC, identification by FT-IR, and impurity profiling, to ensure it meets the high-purity standards required for pharmaceutical and industrial applications. Certificates of Analysis (COA) are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at a controlled room temperature (15-25°C). Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to keep the container under an inert gas blanket (e.g., nitrogen or argon) and ensure it is tightly sealed when not in use to prevent evaporation and degradation. Keep away from heat, sparks, and open flames.
