12-Bromododecanoic Acid丨CAS 73367-80-3

1. Organic Synthesis Intermediate

12-Bromododecanoic acid is widely used as a building block or intermediate in organic synthesis:

Enables nucleophilic substitution reactions via the bromine atom.

Useful for introducing long alkyl chains in chemical synthesis.

Precursor for making amide, ester, and thioester derivatives.

2. Polymer and Surfactant Development

Its amphiphilic nature (hydrophobic tail and polar acid head) makes it valuable in the design of surfactants, emulsifiers, and specialty polymers.

Often modified into functionalized fatty acids or esters to enhance compatibility with synthetic polymers or coatings.

3. Lipid and Membrane Research

Serves as a model compound in lipid research due to its long aliphatic chain.

Studied for its interaction with biomembranes and its behavior in micelle or bilayer formation.

4. Synthesis of Functionalized Materials

Used in preparing self-assembled monolayers (SAMs) and functionalized surfaces by attaching the carboxyl end to solid supports, leaving the alkyl or reactive end exposed for further modification.

5. Medicinal Chemistry and Drug Delivery

Acts as a lipophilic linker or tail in prodrug design, allowing drug molecules to anchor in lipid membranes or enhance bioavailability.

6. Nanomaterial Surface Modification

Applied in surface grafting or tailoring nanostructure properties (e.g., quantum dots, nanoparticles) due to the reactivity of both ends (Br and COOH groups).

✅ Dual Reactivity

The bromine atom enables further substitution with nucleophiles (e.g., amines, thiols), while the carboxylic acid allows for esterification, amide formation, or salt formation.

✅ Versatility

Can be converted into a wide range of derivatives, enabling applications in various industries-from pharma to materials science.

✅ Hydrophobic Tail

The long alkyl chain offers strong hydrophobic interaction, useful in surfactant chemistry, lipid delivery systems, or biointerface design.

✅ Stability and Handleability

As a saturated fatty acid derivative, it is relatively stable under ambient conditions, making it easier to handle and store than more reactive intermediates.

✅ Customizable Functional Groups

Easily modified to tailor physical or chemical properties of molecules or materials for targeted applications.
