Description

4-Piperazinoaniline Dihydrochloride is a high-purity organic salt compound, serving as a critical building block in advanced chemical synthesis. Its value lies in its functionalized piperazine and aniline moieties, which are essential for constructing complex molecular architectures with specific biological or material properties. This intermediate is primarily needed by pharmaceutical R&D teams and fine chemical manufacturers engaged in developing novel active pharmaceutical ingredients (APIs), agrochemicals, and specialty dyes.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders, oncology, and infectious diseases.
• Agrochemical Research: Used in developing advanced herbicides, fungicides, and insecticides that require specific amine-based functional groups.
• Organic Synthesis Building Block: Employed in academic and industrial research laboratories for constructing complex heterocyclic compounds and ligands for catalysis.
• Dye and Pigment Chemistry: Acts as an intermediate in the production of specialized azo dyes and pigments where the aniline derivative imparts specific color and stability properties.
• Material Science: Investigated for use in the synthesis of monomers for advanced polymers, coatings, and functional materials.

Quality Control

Our 4-Piperazinoaniline Dihydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, identity confirmation via IR and NMR spectroscopy, and tests for residual solvents and heavy metals to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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.
