Description

11-Bromo-10-Undecynoic Acid CAS NO 13030-63-2 is a versatile bifunctional organic building block featuring both a terminal alkyne and a bromoalkyl carboxylic acid group. This unique structure makes it a critical intermediate for the synthesis of complex molecules through click chemistry and cross-coupling reactions. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise molecular scaffolds for drug discovery, polymer modification, and ligand synthesis.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs) and prodrugs via Huisgen cycloaddition (click chemistry) and Sonogashira coupling.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators that require specific alkyne-functionalized side chains.
• Polymer & Material Science: Serves as a functional monomer or cross-linker for creating specialty polymers, dendrimers, and surface-modified nanoparticles with tailored properties.
• Bioconjugation & Probe Development: Facilitates the labeling and modification of biomolecules (proteins, peptides, nucleic acids) for diagnostic assays and biochemical research.
• Liquid Crystal & OLED Materials: A precursor for synthesizing advanced organic electronic materials and liquid crystal compounds.
• Organic Synthesis Reagent: A versatile reagent for constructing complex carbon chains and heterocycles in academic and industrial R&D laboratories.
