Description

9-Bromononanoic Acid tert-Butyl Ester is a high-purity, protected bromoalkanoic acid derivative, serving as a versatile and critical building block in advanced organic synthesis. Its value lies in the dual functionality of the reactive bromine handle and the acid-protecting tert-butyl ester group, enabling precise, multi-step molecular construction. This intermediate is essential for researchers and process chemists in the pharmaceutical, agrochemical, and materials science industries, particularly for the synthesis of complex bioactive molecules, liquid crystals, and functional polymers.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), especially in creating long-chain fatty acid analogs, prostaglandins, and other bioactive compounds.
• Agrochemical Synthesis: Used in the production of specialized herbicides, fungicides, and plant growth regulators that require specific alkyl chain modifications.
• Liquid Crystal & OLED Materials: Serves as a precursor for synthesizing mesogenic units and side chains in advanced display and electronic materials.
• Polymer & Material Science: Employed as a monomer or chain extender in the creation of functional polymers, coatings, and specialty materials with tailored properties.
• Cross-Coupling Reactions: An excellent substrate for palladium-catalyzed reactions like Suzuki, Heck, and Negishi couplings to introduce nonanoic acid derivatives into complex structures.
• Peptidomimetics & Bioconjugation: Useful for incorporating fatty acid chains into peptides or for creating linkers in bioconjugation chemistry.
• Organic Synthesis Reagent: A versatile reagent for homologation sequences and the stepwise elongation of carbon chains in complex natural product synthesis.
