Description

Benzoyl Chloride, 3,4-Dinitro- CAS NO 24376-18-9 is a specialized nitro-substituted benzoyl chloride derivative, serving as a critical high-purity intermediate for advanced organic synthesis. Its value lies in the highly reactive acid chloride group and electron-withdrawing nitro substituents, which enable precise and efficient acylation reactions under controlled conditions. This compound is essential for research chemists and process development teams in the pharmaceutical, agrochemical, and specialty chemical industries seeking to synthesize complex molecules, dyes, and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring nitro-aromatic or benzamide motifs.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides where the dinitrobenzoyl moiety imparts specific biological activity.
• Dye and Pigment Manufacturing: Serves as a precursor for azo dyes and other complex colorants, contributing to chromophore development.
• Polymer Chemistry: Employed as a monomer or modifying agent to introduce aromatic nitro groups into polymer chains for specialized material properties.
• Organic Synthesis & Research: A versatile reagent for academic and industrial R&D in nucleophilic acyl substitution reactions to form amides, esters, and ketones.
• Ligand and Complexant Preparation: Useful for synthesizing chelating agents and ligands for metal catalysis and extraction processes.

Quality Control

Every batch of 3,4-Dinitrobenzoyl Chloride is manufactured and tested under strict quality management systems to ensure consistency and reliability for your critical processes. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity, identity, and impurity profiles. Our quality commitment aligns with cGMP principles where applicable, and we support compliance with global regulatory frameworks such as REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (typically 15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent hydrolysis and degradation. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and amines.
