Biological Activity: Terephthalaldehyde is a crosslinking agent. Terephthalaldehyde forms a crosslinked structure inside the gelatin matrix by forming Schiff base imines with the amino groups of gelatin, thereby constructing a three-dimensional network. Terephthalaldehyde improves the hydrophobicity of the gelatin matrix, delays water vapor penetration and enhances the liquid water resistance of gelatin films. Terephthalaldehyde can be used as a crosslinking agent to prepare crosslinked chitosan hydrogel (CAAT) via ultrasound-induced synthesis. Terephthalaldehyde helps CAAT hydrogels selectively adsorb anionic dyes from aqueous media, including multi-component systems containing cationic dyes. Terephthalaldehyde serves as a starting material for the synthesis of bis-heterocyclic compounds (including bis-thiazole and bis-triazolopyrimidine compounds)[1][2][3].
