Description

1,3-Benzenedicarbonyl Dichloride,5-Amino-,Hydrochloride is a high-purity, functionalized aromatic acid chloride derivative, serving as a critical building block in advanced organic synthesis. Its core value lies in providing a reactive di-acid chloride handle with a protected amine group, enabling precise polymer and small molecule construction. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries who require a reliable, high-quality intermediate for creating complex amide-linked structures, dyes, and functional materials.

Application

• Key intermediate in the synthesis of active pharmaceutical ingredients (APIs), particularly for polyamide-based drug candidates.
• Monomer for the production of specialty polyamides and polyimides with enhanced thermal and mechanical properties.
• Building block for advanced agrochemicals, such as herbicides and plant growth regulators with specific targeting.
• Precursor for functional dyes and pigments used in high-performance coatings and imaging technologies.
• Reagent in peptide mimetic and combinatorial chemistry for drug discovery research.
• Cross-linking agent for modifying polymer backbones to introduce specific functional groups or improve material stability.
• Starting material for synthesizing corrosion inhibitors and metal-chelating agents for industrial applications.

Quality Control

Our 1,3-Benzenedicarbonyl Dichloride,5-Amino-,Hydrochloride 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 industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical processes.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from moisture, strong bases, and oxidizing agents.
