Quality Control

Our 4-Bromo-2-Furaldehyde is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including HPLC, GC, and NMR, to verify identity, potency, and impurity profiles. We provide detailed Certificates of Analysis (COA) with every shipment, confirming compliance with agreed specifications. Our quality commitment supports applications requiring GMP-grade intermediates and research chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in amber glass or opaque packaging during storage and handling.
