Quality Control

Our 3,6-Dimethylterephthalaldehyde is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatography (HPLC, GC) and spectroscopic methods (NMR, IR), to verify identity and purity. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality parameters. We support compliance with relevant regulatory frameworks for research and industrial use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at 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.
