O-Phthalaldehyde CAS 643-79-8

1. Excellent Disinfection Performance: Broad-spectrum and highly efficient, it rapidly kills bacteria, viruses, fungi, and spores. It features low irritation, minimal odor, and significantly lower corrosivity compared to glutaraldehyde, causing minimal damage to precision instruments like endoscopes.
2. 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.
3. 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.
4. Good Compatibility: Can be compounded with surfactants and buffer systems, making it adaptable for medical disinfection and analytical reagent formulations.
