Quality Control

Our 4,4'-Iminodibenzoic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets the highest standards of purity and consistency. Certificates of Analysis (COA) detailing specifications such as assay, impurity profile, and physical characteristics are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed after each use to prevent degradation and moisture absorption.
