Quality Control

Our 3-Thiophenecarboxaldehyde, 2,3-Dihydro-3,5-Dimethyl- (9Ci) is produced under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (by GC/HPLC), identity (IR/NMR), and impurity profiles are available upon request. We support custom synthesis and can tailor purity grades to meet specific R&D or cGMP starting material requirements.

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 under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
