Quality Control

Our (2,5-Difluoro-Phenyl)-Acetaldehyde is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical specifications. Our quality commitment supports applications requiring high-purity intermediates under cGMP or ISO 9001 frameworks.

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). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep container tightly sealed under an inert atmosphere (nitrogen or argon) to minimize oxidation and moisture uptake. Isolate from strong oxidizing agents.
