Quality Control

Our n-Butyraldehyde 2,4-Dinitrophenylhydrazone is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity verification and identity confirmation by FT-IR and melting point determination, to ensure it meets the high standards required for analytical applications. A comprehensive Certificate of Analysis (COA) detailing all test results 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, prolonged exposure to light should be avoided to maintain product integrity.
