99% isopropyl alcohol is used:

To clean surfaces, both alone and as a component of a general-purpose cleaner, or as a solvent. 99% isopropyl alcohol has the benefit of being non-corrosive to metals or plastics, so it can be used widely, on all surfaces, and won't leave smears, even on glass or screens.
As an industrial cleaner because it does not leave a residue that may cause complications in manufacturing. Water is a necessary component in most cleaning products, but some electronics and other components cannot come into contact with water. 99% isopropyl alcohol not only cleans these surfaces but evaporates incredibly quickly, leaving the component residue-free.
For disinfecting in pharmaceutical labs, hospitals, and other medical locations. Alcohol is well known for its disinfectant properties, but solutions under 50% significantly lose their effectiveness. 99% isopropyl alcohol is so effective it is suitable for medical and lab-grade applications.
In paint thinners and inks as it is an effective thinner and can be used in paint strippers.
