Quality Control

Our 2,2,3-Trichlorobutyraldehyde is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for synthetic applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, identity, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place, away from heat, sparks, and open flame. Due to its properties as a strong acid/organic solvent and being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep container tightly sealed when not in use to minimize loss due to high volatility.
