Description

6-Bromobenzo[D]Isothiazole-3-Carboxylic Acid is a high-value brominated heterocyclic building block, specifically a benzoisothiazole derivative, essential for advanced organic synthesis. Its core value lies in its versatile reactivity, where the carboxylic acid and bromine substituents serve as orthogonal handles for constructing complex molecular architectures. This compound is critically needed by research chemists and process development scientists in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting neurological disorders and infectious diseases.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and insecticides with enhanced efficacy and selectivity.
• Material Science: Serves as a building block for organic electronic materials, such as OLEDs and semiconductors, due to the electron-deficient benzoisothiazole core.
• Ligand Synthesis: Utilized for creating specialized ligands in catalysis and metal-organic frameworks (MOFs).
• Chemical Biology: Acts as a probe or linker in bioconjugation chemistry for developing diagnostic tools.
• Custom Synthesis: Employed by contract research and manufacturing organizations (CROs/CMOs) for client-specific projects requiring complex heterocycles.

Quality Control

Our 6-Bromobenzo[D]Isothiazole-3-Carboxylic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure high chemical purity and structural integrity. Certificates of Analysis (COA) detailing batch-specific results are provided to guarantee traceability and compliance with your research and development 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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which may affect stability and performance.
