Description

4-Aminosalicylic Acid Oxine is a specialized organic compound derived from salicylic acid, serving as a key intermediate and analytical reagent. Its value lies in its unique bifunctional structure, combining the properties of an aminophenol and an oxine, which makes it a versatile building block for synthesizing more complex molecules and a useful chelating agent. This product is essential for research and development laboratories, pharmaceutical manufacturers, and chemical synthesis operations requiring high-purity intermediates.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs) and diagnostic agents.
• Analytical Chemistry Reagent: Used as a chelating agent and colorimetric reagent for the detection and quantification of specific metal ions in analytical procedures.
• Chemical Synthesis Building Block: Employed in organic synthesis to introduce both phenolic and amino functional groups into target molecules.
• Research & Development: Utilized in academic and industrial R&D for developing new chemical entities, ligands, and coordination complexes.
• Material Science: Potential application in the development of functional materials, such as metal-organic frameworks (MOFs) or polymeric materials.

Quality Control

Our 4-Aminosalicylic Acid Oxine is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR for identification, and loss on drying, to ensure it meets high-grade specifications suitable for research and industrial use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
