Description

Methyl 4-Bromo-3-Formylbenzoate CAS NO 858124-35-3 is a high-purity, multi-functional aromatic ester building block designed for advanced organic synthesis. This compound is valued for its dual reactive sites—the bromo and formyl groups—which enable precise, sequential functionalization in complex molecular architectures. It is primarily required by research chemists and process development scientists in the pharmaceutical, agrochemical, and material science industries for the synthesis of active pharmaceutical ingredients (APIs), ligands, and specialty polymers.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting kinase inhibition and other small-molecule therapeutics.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and plant growth regulators requiring specific halogenated aromatic cores.
• Ligand and Catalyst Development: Serves as a starting material for creating sophisticated chelating ligands used in homogeneous catalysis and metal-organic frameworks (MOFs).
• Material Science Research: Employed in the polymerization and modification of specialty polymers to impart specific electronic or photophysical properties.
• Chemical Biology Probes: Utilized in the design and synthesis of molecular probes for studying enzyme function and cellular processes.
• Custom Synthesis and Contract Manufacturing: An essential building block for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) serving global clients.
