Used as an alkylating agent in organic synthesis, particularly in the production of surfactants and emulsifiers. It is effective in introducing isopropyl groups into various organic molecules, enhancing reactivity in pharmaceutical intermediates and agrochemicals. Also utilized in the preparation of specialty esters and as a sulfating agent in industrial processes where controlled sulfation is required.

Due to its reactivity, particularly its corrosiveness and potential for violent reaction with water, it must be handled with care in moisture-free, controlled environments.
