Quality Control

Our 2-Phenylhydrazonomalonic Acid Hydrogen 1-Ethyl Ester is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Production adheres to current Good Manufacturing Practices (cGMP) where applicable. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We support compliance with global regulatory frameworks including REACH.

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). 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 flames.
