Terephthalaldehyde
Based on 1 Customer Validation
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).

製品説明
体外実験
Terephthalaldehyde (0.005-0.025 g/g gelatin) consistently induces chemical cross-linking of porcine skin gelatin solutions at 60 °C, with a 100% sol-gel transition rate and average gel formation time of 25 min at 0.005 g TPA/g gelatin, while cross-linking is inconsistent or absent at lower temperatures[1].
Terephthalaldehyde (0.025 mol L-1; 25-30 min stirring, 40 min ultrasonication at 40 °C, 2-3 days setting) crosslinks chitosan-acrylic acid to form the CAAT hydrogel, which has a homogeneous porous amorphous structure, high thermal stability, extreme hydrophilicity with 3287% maximum swelling at pH 10, and follows Fickian swelling kinetics[2].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
