Description

Phosgene CAS NO 75-44-5 is a highly reactive, colorless gas at room temperature, widely recognized as a critical chemical intermediate in industrial synthesis. Its primary value lies in its role as a key building block for the production of polycarbonate plastics, isocyanates, and various agrochemicals, enabling the manufacture of essential materials and products. This compound is indispensable for manufacturers in the polymer, pharmaceutical, and specialty chemical sectors who require a reliable and high-purity source for their synthesis processes.

Application

• Polycarbonate Production: A fundamental monomer precursor for manufacturing high-performance, transparent polycarbonate plastics used in electronics, automotive components, and construction.
• Isocyanate Synthesis: Essential for producing toluene diisocyanate (TDI) and methylene diphenyl diisocyanate (MDI), which are the core components of polyurethane foams, coatings, and adhesives.
• Agrochemical Manufacturing: Serves as a key intermediate in the synthesis of important herbicides, insecticides, and fungicides.
• Pharmaceutical Intermediates: Used in controlled syntheses to create specific molecular structures for active pharmaceutical ingredients (APIs).
• Dyestuff and Pigment Production: Acts as a reagent in the manufacture of certain organic dyes and pigments.
• Laboratory and Research: Employed as a specialized reagent in organic chemistry research for carbonylations and other transformations.

Quality Control

Our Phosgene is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and high purity for industrial applications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as purity and critical impurity levels. Our quality protocols are designed to meet the exacting standards required for downstream synthesis in polymer and chemical manufacturing.

Storage

Preserve in a tightly closed, specially designed container, protected from light and moisture. Due to its gaseous and highly toxic nature, storage must be in a dedicated, well-ventilated, and secure area with appropriate gas detection and safety systems. Cylinders must be kept upright, secured, and stored in a cool, dry place away from heat sources and incompatible materials.
