Quality Control

Every batch of 2-Amino-5-(2-Thienyl)Benzoic Acid is manufactured under a strict quality management system and undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Our standard grade typically meets a purity specification of ≥97% (HPLC), with options for higher purity grades (≥98%, ≥99%) available to support critical research and development applications. A detailed Certificate of Analysis (COA) documenting physical characteristics, assay, and impurity profiles is provided with each shipment.

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 sealed to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
