Core Product Advantages

Excellent Disinfection Performance

Broad-spectrum and highly efficient, rapidly kills bacteria, viruses, fungi, and spores. Features low irritation, minimal odor, and significantly lower corrosivity compared to glutaraldehyde, causing minimal damage to precision instruments like endoscopes.

High Detection Sensitivity

Reacts rapidly with primary amines to generate strong fluorescence, enabling trace-level detection at the pmol scale with a fast reaction rate.

Strong Chemical Reactivity

Its dialdehyde structure easily undergoes condensation and addition reactions, making it highly suitable for organic synthesis and the synthesis of pharmaceutical intermediates.

Good Compatibility

Can be compounded with surfactants and buffer systems, making it adaptable for medical disinfection and analytical reagent formulations.
