About

CSIR-CSMCRI has developed a green brominating reagent - a better alternative to the hazardous liquid bromine. This green brominating agent is an attractive source of bromine for bromination of various organic substrates. The reagent has been designed for three main functionalities 1) Brominating Reagent for Substitution (BR-S); 2) Brominating Reagent for Addition Reactions (BR-A); and 3) Brominating Reagent for Oxidations (BR-O). The reagent can be prepared cost-effectively from the intermediate of bromine recovery plants.
