Uses

Used in Fluorescence-based Sensor Applications:
Benzaldehyde-2,4-disulfonic acid disodium salt is used as a key intermediate in the synthesis of symmetric and asymmetric xanthene dyes. These dyes are essential components in the development of fluorescence-based sensors, which are crucial for imaging applications in various fields, including biomedical research and diagnostics.
Used in Ultraviolet Radiation Protection:
Benzaldehyde-2,4-disulfonic acid disodium salt is also utilized in the synthesis of oxadiazole-based stilbene optical brighteners. These brighteners serve as ultraviolet radiation protectants, particularly for insect baculoviruses. By incorporating these protectants, the integrity and effectiveness of the baculoviruses can be maintained, which is vital for their use in biological pest control and other applications.

Structure-stability correlations for imine formation in aqueous solution

Imine formation between 25 aldehydes and 13 amines in aqueous solution in the pH range 7-11 was studied by 1H NMR spectroscopy. A three-parameter linear equation correlating logarithms of imine formation constants with pKa and HOMO energies of amines and LUMO energies of aldehydes is proposed. In view of the widespread occurrence of imine-forming processes in both chemistry and biology, the data presented are of significance for physical organic chemistry and of particular interest for dynamic combinatorial chemistry.
