Merck, 76492-25G, 10,12-Pentacosadiynoic acid

Application
10,12-Pentacosadiynoic acid (PCDA) is an amphiphilic diacetylene that can be used:
In combination with a semifluorinated tetracosane ((CF₃(CF₂)₇(CH₂)₁₅CH₃) to synthesize mixed monolayer by photopolymerization.
For the conversion of hydrophobic upconverting nanoparticles (UCNPs) to hydrophilic.
To synthesize a polymer by combining with pyridine-2-aldoxime for colorimetric detection of malathion.
To synthesize a thermochromic sensor constituting polymer fibres with monomeric unit of two PCDA linked by a p-phenylene group (bis-PCDA-Ph).
As an inert coating material upon self-assembly and photopolymerization to modify the surface of Fe₃O₄nanoparticles.
