Description

Benzothiazole, 4-Ethenyl-5-Isothiocyanato- (9Ci) is a specialized heterocyclic organic compound featuring both a benzothiazole core and reactive ethenyl and isothiocyanate functional groups. This unique molecular architecture makes it a valuable high-purity intermediate for advanced chemical synthesis, particularly in the development of novel functional materials and active pharmaceutical ingredients (APIs). It is primarily sought by research institutions, fine chemical manufacturers, and pharmaceutical R&D departments for applications in medicinal chemistry, polymer science, and agrochemical research.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel drug candidates, particularly those targeting specific enzyme inhibition or receptor modulation.
• Agrochemical Research: Used in the development of new fungicides, herbicides, or plant growth regulators due to the bioactive benzothiazole scaffold.
• Polymer & Material Science: Acts as a functional monomer or cross-linking agent for creating specialty polymers with tailored thermal, optical, or mechanical properties.
• Chemical Synthesis Reagent: Employed in organic synthesis to introduce the benzothiazole moiety or as a precursor for more complex heterocyclic systems.
• Ligand & Catalyst Development: Utilized in coordination chemistry for the design of novel ligands for metal complexes used in catalysis or sensing applications.
• Dye & Pigment Intermediate: Potential use in the synthesis of specialized dyes and organic pigments for high-performance applications.

Quality Control

Our production of Benzothiazole, 4-Ethenyl-5-Isothiocyanato- (9Ci) adheres to stringent internal quality standards to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including HPLC, GC, NMR, and IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment. We support cGMP and ISO 9001 compliant manufacturing practices for research and commercial scale requirements.

Storage

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