Description

2(3H)-Benzothiazolone,6-Fluoro-5-Isocyanato-(9Ci) is a specialized heterocyclic building block that combines a benzothiazolone core with a reactive isocyanate group and a fluorine substituent. This unique structure makes it a critical intermediate for synthesizing advanced molecules with tailored biological or material properties. It is primarily sought after by research and development chemists in the pharmaceutical and agrochemical industries for creating novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in the development of kinase inhibitors, anti-inflammatory agents, and other small molecule therapeutics.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, where the fluorine atom and heterocyclic core can enhance biological activity and environmental stability.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of specialty polymers, coatings, and resins with specific thermal or chemical resistance properties.
• Chemical Biology Probes: Utilized in the creation of activity-based probes and labeling reagents due to the reactive isocyanate group, which can form stable bonds with amines and hydroxyls.
• Dye and Pigment Intermediate: Potential precursor for synthesizing specialized fluorinated heterocyclic dyes and optical brighteners.

Quality Control

Our 2(3H)-Benzothiazolone,6-Fluoro-5-Isocyanato-(9Ci) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets the high standards required for research and process development. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation from atmospheric moisture.
