Quality Control

Our 2,5-Bis(octyloxy)terephthalaldehyde is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC, to ensure the minimum 98% purity specification is met. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee batch-to-batch consistency and traceability for your R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider keeping under an inert atmosphere such as nitrogen or argon. Keep away from heat, sparks, and open flame.
