Description

1,2-Benzenedicarbonyl Dichloride,3-Nitro- CAS NO 24564-71-4 is a high-purity nitro-substituted aromatic acid chloride derivative, serving as a critical reactive intermediate in advanced organic synthesis. Its value lies in the dual functionality of the acid chloride groups, which readily undergo nucleophilic substitution reactions, and the nitro group, which offers a versatile handle for further chemical transformations. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries who require a reliable building block for constructing complex molecules, such as active pharmaceutical ingredients (APIs) and functional dyes.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of nitro-substituted phthalimide derivatives and other complex heterocycles used in drug discovery and development.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators where the nitro-aromatic moiety is required for biological activity.
• Polymer Chemistry: Monomer for the creation of specialty polyimides and polyamides with enhanced thermal stability and specific optical properties.
• Dye and Pigment Manufacturing: Intermediate in the synthesis of high-performance nitro-substituted pigments and optical brighteners.
• Ligand and Chelating Agent Precursor: Starting material for synthesizing specialized ligands used in catalysis and metal ion sequestration.
• Cross-linking Agent: Utilized in the modification of polymers and resins to introduce cross-links, improving mechanical and chemical resistance.

Quality Control

Our 1,2-Benzenedicarbonyl Dichloride,3-Nitro- is produced 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 sensitive synthetic 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, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong acids, bases, and oxidizing agents.
