Description

3,4-Dibromophenylisothiocyanate is a versatile and reactive organobromine compound that serves as a critical building block in advanced organic synthesis. Its unique structure, featuring both bromine substituents and a highly electrophilic isothiocyanate group, makes it an invaluable reagent for constructing complex heterocycles and functionalized aromatic systems. This high-purity intermediate is essential for research and development chemists in the pharmaceutical, agrochemical, and material science industries, enabling the creation of novel active ingredients and specialty chemicals.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of potential drug candidates, particularly those targeting neurological disorders and oncology, where the dibromophenyl moiety can modulate bioavailability and receptor binding.
• Agrochemical Synthesis: Used to develop novel herbicides, fungicides, and insecticides, leveraging the reactivity of the isothiocyanate group to introduce sulfur-containing bioactive scaffolds.
• Ligand and Catalyst Development: Serves as a starting material for synthesizing specialized ligands for metal catalysis and coordination chemistry, useful in asymmetric synthesis and polymerization processes.
• Material Science Research: Employed in the creation of monomers for advanced polymers, liquid crystals, and organic electronic materials due to its aromatic backbone and dual functionalization.
• Chemical Biology Probe: Useful for bioconjugation and labeling studies, as the isothiocyanate group can react with amine groups on proteins and peptides under mild conditions.
• Heterocyclic Chemistry: Fundamental building block for the construction of benzothiazole, quinazoline, and other nitrogen-sulfur heterocycles of industrial and research interest.

Quality Control

Our 3,4-Dibromophenylisothiocyanate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity assessment, NMR and IR for structural confirmation, and residual solvent analysis. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment, ensuring full traceability and compliance with your research or production 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 (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.
