Product Introduction
4-Nitrobenzoyl chloride (CAS 122-04-3), frequently abbreviated as PNBC, is an organic compound with the molecular formula C7H4ClNO3. It appears as a yellow crystalline solid with a pungent odor. As a highly reactive aromatic acid chloride, 4-Nitrobenzoyl chloride (CAS 122-04-3) is a cornerstone of organic synthesis, serving as a powerful acylating agent. It is primarily used to introduce the 4-nitrobenzoyl group into various substrates, making it indispensable for the production of pharmaceuticals, agricultural chemicals, and high-quality dyes.
Product Selling Points

Applications
Pharmaceutical Synthesis The most critical application is the production of local anesthetics (e.g., Procaine hydrochloride) and various antibiotics. It is also a precursor for folate-related research compounds.
Dye and Pigment Industry Used in the synthesis of high-performance organic pigments and azo dyes, specifically for introducing the nitro-aromatic moiety which enhances color fastness and stability.
Agricultural Chemicals Serves as an intermediate for the manufacture of specialized herbicides and fungicides.
Polymer and Material Science Utilized as a monomer or modifying agent in the production of specialized aromatic polyamides and liquid crystal polymers.
Chemical Reagent Commonly used in laboratories for the derivatization of amines and alcohols to facilitate their identification and analysis via chromatography.
Packaging
Standard industrial packaging options for 4-Nitrobenzoyl chloride include:
-
25kg fiber drums with double-layer, high-density PE moisture-proof inner bags (Standard export packaging).
-
50kg reinforced plastic drums for specialized industrial handling.
-
All packaging is nitrogen-blanketed to ensure zero moisture contact and is labeled as Corrosive (Class 8) in accordance with UN regulations.
Storage
4-Nitrobenzoyl chloride is moisture-sensitive and corrosive. It must be stored in a cool, dry, and well-ventilated dedicated warehouse. Keep containers tightly sealed at all times. Protect from atmospheric moisture, as it reacts with water to form 4-nitrobenzoic acid and corrosive hydrogen chloride gas. Store away from strong bases, alcohols, and oxidizing agents. Properly stored in its original, unopened container, it has a shelf life of 12 months.
