Atomfair 4-Aminomethylbenzoic acid PAMBA, 4-AMBA, NA C8H9NO2 CAS 56-91-7

Description

4-Aminomethylbenzoic Acid (PAMBA) is a high-purity pharmaceutical intermediate and research chemical with the molecular formula C₈H₉NO₂ (CAS: 56-91-7). This white crystalline powder is widely recognized for its role as a hemostatic agent, functioning as a competitive inhibitor of plasminogen activation. With a melting point of ~250°C (dec.) and solubility in water, dilute acids, and alkalis, it is ideal for biochemical and pharmacological applications. Our product is rigorously tested via HPLC (>97% purity) and meets EP/USP standards, ensuring consistency for drug development, clinical research, and analytical reference. Packaged in amber glass vials under inert gas to prevent degradation. Synonyms include Tranexamic Acid Impurity D, 4-Carboxybenzylamine, and Styptopur.

4-Aminomethylbenzoic acid is primarily used as an antifibrinolytic agent to reduce bleeding by inhibiting plasminogen activation. It serves as a key reference standard in QC laboratories for hemostatic drug analysis (e.g., Tranexamic Acid formulations). Researchers also employ it in studying serine protease inhibition mechanisms and developing novel anticoagulant therapies.
