Product Identification
Synonyms: 1-Bromo-3-fluoro-2-iodobenzene, 2-Iodo-3-Bromofluorobenzen
CAS No.: 450412-29-0
Molecular formula: C6H3BrFI
Molecular weight: 300.89
Boiling point: 249 ºC
Density: 2.281g/mL @ 25°C
Flash point: 104 ºC
Refractive index: 1.6354

Specification
Appearance: Pale-yellow to colorless transparent liquid
Purity: 98.00%min by GC

Package
Regular Packing: N.W 20kg/plastic drum
Sample Packing: 0.1kg-1kg plastic bottle or under request


Transportation Information
Classification: Non-dangerous goods
HS Code: 2903999090

Status & Application
Status: commercial available
Application:
1) OLED intermediate
2) Organic synthesis
    For example:

Two new scalable methods for the synthesis of dibenzo[bc,fg]dithiapentalene (2) (DPP) are reported starting from either 1-bromo-3-fluoro-2-iodobenzene over four steps in 57% yield or from THP-protected 3-fluorothiophenol over three steps in 43% yield. Attempts to prepare dibenzodioxapentalene (15) using similar conditions were unsuccessful. Instead, we observed the formation of a macrocyclic dimeric product 16. Fluorine-hydrogen bond interactions were observed by NMR in the F/SH- and F/OH-substituted dibenzothiophene and dibenzofuran intermediates.
