Description

Chlorocarbonic Acid CAS NO 463-73-0 is a highly reactive chemical intermediate, also known as phosgene, which is a cornerstone reagent in organic synthesis. Its primary commercial value lies in its ability to introduce the carbonyl group and serve as a chlorinating agent, enabling the efficient production of a wide range of industrial and pharmaceutical compounds. This product is essential for manufacturers in the agrochemical, pharmaceutical, and polymer industries, where it is used to synthesize isocyanates, carbonates, and other high-value derivatives.

Application

• Isocyanate Production: A key raw material for manufacturing toluene diisocyanate (TDI) and methylene diphenyl diisocyanate (MDI), which are essential for polyurethane foams, coatings, and adhesives.
• Pharmaceutical Intermediates: Used in the synthesis of active pharmaceutical ingredients (APIs), including certain antibiotics, herbicides, and insecticides.
• Polycarbonate Resins: Serves as a monomer in the production of high-performance polycarbonate plastics via interfacial polymerization.
• Agrochemical Synthesis: Employed in the manufacture of herbicides, fungicides, and other crop protection agents.
• Chlorinating Agent: Used in organic synthesis to convert hydroxyl groups into chlorides or to produce acid chlorides from carboxylic acids.
• Dye and Pigment Manufacturing: Acts as an intermediate in the production of certain organic dyes and pigments.

Quality Control

Our Chlorocarbonic Acid is produced and handled under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and impurity profiling, to ensure it meets exacting standards for industrial and fine chemical synthesis. Certificates of Analysis (COA) with detailed specifications are provided for each shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed, properly rated pressure container, protected from light and moisture. Due to its highly volatile and gaseous nature under standard conditions, it must be stored in a cool, well-ventilated area, away from heat sources and incompatible materials such as water, alcohols, amines, and strong bases. Storage temperature should be maintained as recommended for the specific container and formulation. Handle only in equipment designed for toxic and corrosive gases.
