Quality Control

Our 4-Formyl-α-Methyl-Benzeneacetic Acid Ethyl Ester is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee compliance with your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is easily oxidized and should be handled under an inert atmosphere for long-term storage or when opening containers to maintain purity. Keep away from heat, sparks, and open flame.
