Description

4-(3-Aminopropyl)Aniline 2Hcl is a high-purity, bifunctional organic building block featuring both a primary aromatic amine and a primary aliphatic amine group, each in their hydrochloride salt form. This dual functionality makes it a critical intermediate for the synthesis of complex molecules, offering enhanced solubility and stability for downstream reactions. It is primarily sought after by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for developing active ingredients, ligands, and advanced materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a diamino linker or for creating heterocyclic structures.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators where its aromatic and aliphatic amine groups can be selectively modified.
• Polymer & Material Science: Serves as a monomer or cross-linking agent for producing polyamides, polyimides, and other high-performance polymers with specific thermal and mechanical properties.
• Dye & Pigment Manufacturing: Acts as a diazo component or coupling agent in the production of azo dyes and organic pigments, contributing to color fastness and molecular structure.
• Bioconjugation & Linker Chemistry: Utilized in biochemical research for creating cleavable or stable linkers in antibody-drug conjugates (ADCs) and other bioconjugates.
• Catalyst & Ligand Preparation: Employed to synthesize chelating ligands for metal catalysts used in asymmetric synthesis and other catalytic processes.

Quality Control

Our 4-(3-Aminopropyl)Aniline 2Hcl is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your project requirements.

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 (moisture-sensitive) nature, the container must be kept sealed under dry, inert conditions to prevent degradation and clumping.
