Description

Methyl 2-Bromo-5-Cyano-4-Fluorobenzoate is a high-value, multi-functional aromatic building block designed for advanced organic synthesis. Its unique combination of bromo, cyano, and fluoro substituents on a benzoate ester core makes it a critical intermediate for constructing complex molecules with tailored electronic and steric properties. This compound is primarily utilized by research chemists and process development scientists in the pharmaceutical and agrochemical industries for the synthesis of active ingredients and novel chemical entities.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of kinase inhibitors, anti-cancer agents, and other small-molecule therapeutics.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides, where the fluorine and cyano groups enhance biological activity and metabolic stability.
• Material Science Precursor: Serves as a monomer or functionalization agent in the development of specialty polymers, liquid crystals, and organic electronic materials.
• Cross-Coupling Reactions: The bromo substituent makes it an excellent substrate for palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck, Sonogashira) to create complex biaryl structures.
• Fluorine Chemistry Research: An important reagent for studying the effects of fluorine introduction on molecular properties like lipophilicity, bioavailability, and binding affinity.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for custom synthesis projects and scale-up campaigns.

Quality Control

Our Methyl 2-Bromo-5-Cyano-4-Fluorobenzoate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is subjected to rigorous analytical testing, including HPLC, GC, NMR, and mass spectrometry, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We support cGMP (current Good Manufacturing Practice) standards for applications requiring the highest level of quality assurance.

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 and consideration should be given to storage under an inert atmosphere for long-term preservation of quality. Keep away from heat and incompatible materials.
