Description

m-Nitrobenzoyl Chloride CAS NO 121-90-4 is a versatile and reactive aromatic acid chloride derivative, serving as a critical building block in advanced organic synthesis. Its primary value lies in its ability to efficiently introduce the m-nitrobenzoyl moiety, a key functional group for modifying molecular properties and bioactivity. This high-purity intermediate is essential for research and production chemists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to develop new active compounds and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring a meta-substituted benzamide or ester functionality.
• Agrochemical Synthesis: Used in manufacturing herbicides, fungicides, and plant growth regulators where the nitro group is a crucial pharmacophore.
• Dyestuff and Pigment Production: Serves as an intermediate for azo dyes and other complex colorants, contributing to color fastness and molecular stability.
• Polymer Chemistry: Employed as a monomer or modifying agent for engineering plastics and high-performance polymers to enhance thermal or mechanical properties.
• Liquid Crystal and OLED Materials: Acts as a synthetic building block for advanced electronic materials requiring specific dipole moments and conjugation.
• Chemical Research & Development: A valuable reagent in academic and industrial R&D for exploring new reaction pathways and creating novel chemical entities.

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 and highly volatile nature, keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition. Keep away from strong bases, oxidizers, and sources of ignition.
