85-22-3 Usage
Chemical Properties
2,3,4,5,6-Pentabromoethylbenzene is a solid of high bromine content (80 wt %) with a melting point of 136-138°C and a decomposition temperature of ca 210°C. The compound is prepared by the Friedel-Crafts-catalyzed bromination of ethyl benzene in an inert solvent. Its manufacturers recommends its use in epoxy resins, ABS and urethane foams.
Uses
Pentabromoethylbenzene is a flame retardant and a standard for environmental testing and research.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Simple aromatic halogenated organic compounds, such as 2,3,4,5,6-PENTABROMOETHYLBENZENE, are very unreactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.
Fire Hazard
Flash point data for 2,3,4,5,6-PENTABROMOETHYLBENZENE are not available; 2,3,4,5,6-PENTABROMOETHYLBENZENE is probably combustible.
Safety Profile
Low toxicity by skin contact. When heated to decomposition it emits toxic vapors of Brí.
Check Digit Verification of cas no
The CAS Registry Mumber 85-22-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 85-22:
(4*8)+(3*5)+(2*2)+(1*2)=53
53 % 10 = 3
So 85-22-3 is a valid CAS Registry Number.
