Description

2-Butanone, 4-Isocyanato- (9Ci) is a specialized isocyanate derivative of 2-butanone, serving as a versatile and reactive chemical building block. This compound is valued for its ability to introduce isocyanate functionality into target molecules, enabling the synthesis of polymers, coatings, and fine chemicals. It is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials industries for applications requiring controlled reactivity and specific molecular architecture.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring urethane or urea linkages.
• Agrochemical Synthesis: Serves as a key precursor in the production of herbicides, fungicides, and pesticides, where its reactive isocyanate group facilitates the formation of bioactive compounds.
• Polymer & Resin Modification: Employed as a cross-linking agent or chain extender in the manufacture of polyurethanes, coatings, adhesives, and specialty elastomers to enhance mechanical and chemical resistance properties.
• Fine Chemical Production: Acts as a versatile reagent for introducing the isocyanate moiety in custom synthesis and the production of complex organic molecules for research and industrial applications.
• Surface Coating Formulations: Utilized in the development of high-performance industrial and protective coatings that demand excellent durability and adhesion.

Quality Control

Our 2-Butanone, 4-Isocyanato- (9Ci) is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by GC or HPLC, identity confirmation (IR), and impurity profiling, to ensure it meets the high-purity standards required for synthetic applications. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation. Isolate from moisture, heat, and incompatible materials such as alcohols, amines, and strong bases.
