Description

2,5-Diaminoindan Dihydrochloride is a high-purity, di-functionalized indane derivative that serves as a critical chiral building block and intermediate in advanced organic synthesis. Its value lies in its rigid, fused-ring structure and dual amine functionality, which are essential for constructing complex molecules with specific stereochemistry and biological activity. This compound is primarily needed by research institutions and pharmaceutical companies engaged in the development of active pharmaceutical ingredients (APIs), agrochemicals, and specialty fine chemicals, particularly for applications requiring precise molecular architecture.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of novel drug candidates, including potential central nervous system (CNS) agents and enzyme inhibitors.
• Agrochemical Research: Building block for developing advanced pesticides and herbicides with targeted modes of action.
• Ligand Synthesis: Precursor for creating chiral ligands used in asymmetric catalysis and metal complexation.
• Polymer Chemistry: Monomer or cross-linking agent for specialty polymers, such as polyamides or epoxy resins, requiring enhanced thermal or mechanical properties.
• Dye and Pigment Intermediate: Used in the synthesis of complex organic colorants and functional dyes.
• Academic & R&D: Serves as a standard or starting material in methodological studies and discovery chemistry within university and corporate laboratories.

Quality Control

Our 2,5-Diaminoindan Dihydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 conditions to prevent degradation.
