Quality Control

Every batch of Propanoic Acid, 2-(4-Ethylphenoxy)-, Hydrazide (9Ci) is manufactured under strict quality management systems. We employ advanced analytical techniques including HPLC, GC-MS, and NMR to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality and regulatory requirements.

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 stability. Keep away from heat, sparks, and open flame.
