Quality Control

Every batch of 2-(4-Chloro-3-Fluorophenyl)Acetaldehyde is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemical intermediates. Comprehensive analytical testing, including HPLC, GC, and NMR, is performed to verify identity, purity, and impurity profiles. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

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