Chemical Properties

white to light yellow crystal powde

Uses

α,α′?Dichloro-o-xylene was used in solid-phase synthesis of large combinatorial variations of fundamental peptide unit.

Uses

1,2-Bis(chloromethyl)benzene is used in solid-phase synthesis of large combinatorial variations of fundamental peptide unit 1 .

General Description

α,α′-Dichloro-o-xylene reacts with elemental tellurium and NaI in 2-methoxyethanol to form 1,1-diiodo-3,4-benzo-1-telluracyclopentane.

Safety Profile

Poison by intravenous route. Mutation data reported. See also CHLORINATED HYDROCARBONS, AROMATIC. When heated to decomposition it emits toxic Cl-.
