Purecha Group: We specialize in Fine 4-Bromo benzaldehyde Chemicals, Specialty Chemicals and Bromination Compounds. Our company's future is one of leadership in a 4-Bromo benzaldehyd and widening spectrum of Specialty market. 4-Bromo Benzaldehyde will react with alkenes in aqueous solvents to give bromohydrins and preferred conditions are the portionwise addition of NBS to a solution of the alkene in 50% aqueous DMSO, DME, THF. Formation of a bromonium ion and immediate attack by water gives strong Markovnikov addition and anti stereochemical selectivities.

5. Diphenyl Acetonitrile It self has only a modest toxicity, but it can be metabolised to produce hydrogen cyanide (see below), which is the source of the observed toxic effects. The relatively slow metabolism of Diphenyl Acetonitrile to hydrogen cyanide allows more of the cyanide produced to be detoxified with in the body to thiocyanate.
