Description

4-tert-Butylcalix[4]arene-tetraacetic acid triethyl ester is a functionalized calixarene derivative, a key intermediate in supramolecular chemistry for creating highly selective host molecules. Its value lies in the pre-organized cavity structure, which can be further modified to bind specific metal ions or organic guests with high affinity and selectivity. This compound is essential for researchers and manufacturers in the fields of chemical sensors, ion-selective electrodes, and advanced separation technologies.

Application

• Key intermediate for synthesizing ionophores and cation-selective ligands.
• Building block for supramolecular receptors targeting heavy metal ions or rare earth elements.
• Precursor in the development of chemical sensors and potentiometric membrane electrodes.
• Component in extraction agents for metal recovery and separation processes.
• Research chemical for studying host-guest chemistry and molecular recognition.
• Starting material for functionalized materials used in catalysis and nanotechnology.
