• Chemische Eigenschaften

  Colorless to pale yellow liquid

• Verwenden

  3-Bromobiphenyl is utilized as an electrochemical immunosensor based on poly(dopamine) coated gold nanocluster for brominated flame retardants.

• Definition

  T3DB: 3-Monobromobiphenyl is a polybrominated biphenyl. Polybrominated biphenyls (PBBs) are a group of 209 synthetic organic compounds with 1-10 bromine atoms attached to biphenyl. They can be used as flame retardants and may be added to the plastics used to make products like computer monitors, televisions, textiles, and plastic foams to make them difficult to burn. However, the use of PBBs is banned or restricted in most areas due to their toxicity and persistence in the environment.

• Brandgefahr

  Flash point data for 3-Bromobiphenyl are not available. 3-Bromobiphenyl is probably combustible.

• Toxikologie

  The exact mechanism of toxicty of PBBs varies depending on the specific congener. The predominant interaction is believed to involve the aryl hydrocarbon receptor (AhR). PBBs bind to and activate the AhR, which in turn initiates the transcriptional upregulation of a number of genes, affecting biochemical and endocrine pathways, cell cycle regulation, morphogenesis, oxidative stress response, and various other processes. This results in the numerous toxic responses characteristic of PBBs. Some of the known induced genes include the cytochrome P-450-dependent monooxygenases CYP1A1 and CYP1A2.

• Research

  3-Bromobiphenyl could be prepared by irradiation of 3,4-dibromobiphenyl (BpBr2) in acetonitrile. At present, a variety of detection methods have been developed to detect its concentration. Such as the electrochemical immunoassay of 3-BBP based on the PDOP/PB/CMK-3 platform and the multi-HRP–DHCNTs–Ab2 signal label. This detection method can detect the concentration of 3-Bromobiphenyl in the environment (This study takes river water from the estuary of the Pearl River as sample solvent)[1-2].
