Quality Control

Our 2-[3-(n-Ethylbutyrylamino)-2,4,6-Triiodophenoxy]Butyric Acid is manufactured under strict quality systems to meet the exacting standards required for pharmaceutical intermediates. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We ensure compliance with relevant ICH guidelines and can support customer audits for GMP-grade material intended for drug substance synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry 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 strong oxidizing agents.
