Quality Control

Our 5-Ethyl-2-Hydroxyisophthalaldehyde is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical documentation, including a detailed Certificate of Analysis (COA) for each batch, verifying identity, purity, and impurity profiles. Our quality control protocols are designed to meet the stringent requirements of our global customer base in advanced research and regulated synthesis.

Storage

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