p-Xylylenediamine

p-Xylylenediamine (p-XDA) is an aromatic diamine monomer characterized by its two primary amino groups and rigid aromatic structure, which contribute to its exceptional thermal stability and mechanical strength. Its reactivity allows for versatile functionalization and effective cross-linking, making it a suitable building block in polymer synthesis. p-XDA′s solubility in organic solvents facilitates its incorporation into various formulations, including hydrogels for drug delivery systems.

p-Xylylenediamine can be used:

• As a monomer to synthesize ultra heat-resistant thermoplastic polyamide elastomers suitable for high-temperature applications. It contributes to increased tensile strength, toughness, and Young′s modulus of the elastomer, thereby enhancing its overall mechanical strength.
• As a cross-linking agent to prepare solvent resistant high performance nanofiltration membranes. p-Xylylenediamine facilitates superior separation performance and stability for N,N-dimethylformamide (DMF) solution.
• As a dendrimer core to synthesize stimuli responsive nanocarriers for cancer drug delivery.
• As a capping agent to prepare fluorescent organic–inorganic hybrid CH₃NH₃PbBr₃ nanocrystals to fabricate 3D-printed paper-based microfluidic optical sensor for naked-eye detection of picric acid.
