Quality Control

Every batch of 3-(4-Carboethoxy)Phenyl Propanal is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the high-purity standards required for sensitive synthetic applications. A detailed Certificate of Analysis (COA) is supplied with each shipment, reporting key parameters such as identity (IR, NMR), purity (HPLC), and specific impurity profiles. Our quality commitment supports compliance in cGMP and ISO 9001 environments for pharmaceutical and industrial customers.

Storage

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