CAS 91-13-4

1,2-Bis(bromomethyl)benzene

Description:

1,2-Bis(bromomethyl)benzene, with the CAS number 91-13-4, is an organic compound characterized by its structure, which features a benzene ring with two bromomethyl groups (-CH2Br) attached to the first and second carbon atoms. This compound is typically a colorless to pale yellow liquid and is known for its reactivity due to the presence of bromine atoms, which can participate in various chemical reactions, including nucleophilic substitutions. It is used in organic synthesis, particularly in the preparation of more complex molecules and as an intermediate in the production of pharmaceuticals and agrochemicals. The compound is also notable for its potential applications in polymer chemistry. However, it should be handled with care due to the toxicity associated with brominated compounds and the potential for environmental persistence. Proper safety measures, including the use of personal protective equipment and working in a well-ventilated area, are essential when working with this substance.

o-Xylylene dibromide

CAS: 91-13-4

o-Xylylene dibromide is a diphosphine that is used as an antibacterial agent. It inhibits bacterial growth by binding to the iron of the active site of the enzyme ribonucleotide reductase. This prevents the production of DNA and RNA, which are essential for protein synthesis and cell division. The reaction mechanism is thought to involve a Friedel-Crafts reaction between o-xylylene dibromide and hydroxide solution, followed by a metal ion catalysed elimination reaction with imine or tetradentate ligands, such as malonic acid.
