Quality Control

Our 1,3-Cyclopentadiene-1-Carboxaldehyde, 5-[(Dimethylamino)Methylene]- is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity for research and scale-up applications. While typically supplied at research-grade purity (>95%), specifications for HPLC/GC assay, identity confirmation (IR, NMR), and impurity profiling are established for each lot. A comprehensive Certificate of Analysis (COA) detailing all relevant parameters is provided with every shipment.

Storage

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