Description

21-Bromoheneicosanoic Acid is a high-purity, long-chain brominated fatty acid derivative, serving as a critical synthetic intermediate in advanced organic chemistry. Its value lies in the strategic placement of the bromine atom, which provides a versatile handle for further functionalization via cross-coupling or nucleophilic substitution reactions. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science sectors, particularly for the synthesis of complex lipids, liquid crystals, and bioactive molecules.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, especially those targeting lipid metabolism or requiring long alkyl chain modifications.
• Agrochemical Research: Used in the development of new surfactants, emulsifiers, and active ingredients with tailored hydrophobic properties.
• Materials Science: Serves as a precursor for synthesizing specialized monomers used in polymers, coatings, and liquid crystalline materials.
• Biochemical Probe Development: Utilized in labeling studies and the creation of fluorescent or tagged fatty acid analogs for biological research.
• Organic Synthesis: A versatile reagent for carbon-chain elongation and the introduction of functional groups in complex molecule construction.
