Quality Control

Our 4-Amino-3-Hydroxybenzoic Acid Ethyl Ester 97% is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets the declared specification of 97% minimum purity and is free from critical impurities. Certificates of Analysis (COA) detailing identity, purity, and related substances are 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
