Description

Benzoyl Chloride, 4-Nitroso- (9Ci) is a specialized benzoyl chloride derivative characterized by the presence of a nitroso functional group at the para position. This reactive intermediate is crucial for introducing the 4-nitroso-benzoyl moiety into target molecules, enabling advanced synthesis in fine chemical and pharmaceutical research. It is primarily sought by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring a nitroso-benzoyl functional group.
• Agrochemical Synthesis: Used in the research and development of advanced pesticides, herbicides, and plant growth regulators.
• Dye and Pigment Precursor: Serves as a critical intermediate in the production of specialized azo dyes and organic pigments.
• Polymer Chemistry: Employed to modify polymers or as a monomer for creating polymers with specific light-absorbing or chemical properties.
• Chemical Research & Development: A valuable reagent in academic and industrial labs for exploring new organic reactions and synthesizing complex heterocyclic compounds.
• Ligand and Catalyst Preparation: Used to synthesize specialized ligands for metal complexes and catalysts used in asymmetric synthesis.

Quality Control

Our Benzoyl Chloride, 4-Nitroso- (9Ci) is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity for research and development applications. Each lot is analyzed using advanced techniques including HPLC, NMR, and IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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 degradation. Keep away from strong acids, bases, and oxidizing agents.
