Quality Control

Our 5-Chloro-2,3-Dihydrobenzofuran-7-Carbaldehyde is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all specifications and test results. Our quality commitment supports applications requiring high-purity intermediates, from research to pilot-scale production.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
