- InChl : 1S/C20H20P.BrH/c1-2-21(18-12-6-3-7-13-18,19-14-8-4-9-15-19)20-16-10-5-11-17-20;/h3-17H,2H2,1H3;1H/q+1;/p-1
- Substance type: Organic
- Physical state: Solid
- Physical Appearance: white powder
- Purity: 98.6%
- Storage Conditions: 1. Ambient Temp (23 to 27 °C) √ (Store in a cool place. Keep containers tightly closed in a dry and well ventilated place) - Key result
- Test procedure:
- ignition time on contact with air
- Remarks:
- Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
- Remarks on result:
- no ignition on contact with air (not further specified)
- Remarks:
- corresponding to 'no' in migrated source record. | Remarks: | Additional remarks: Ethyltriphenylfosfonium bromide ignited when the flame of bunsen burner having temperature of 950 degC was brought in contact with it.
- Key result

- Interpretation of results:
- non flammable
- Conclusions:
- From the experimental values of flammability,ethyltriphenylfosfonium bromideignited when the flame of bunsen burner having temperature of 950 degC was brought in contact with it. Thus it can be concluded thatethyltriphenylfosfonium bromide is flammable only at high temperature of about 950 degC. However since such high temperatures are not found under normal circumstances of transportation and use,ethyltriphenylfosfonium bromidewas considered non-flammable.
- Executive summary:
From the experimental values of flammability,ethyltriphenylfosfonium bromideignited when the flame of bunsen burner having temperature of 950 degC was brought in contact with it. Thus it can be concluded thatethyltriphenylfosfonium bromide is flammable only at high temperature of about 950 degC. However since such high temperatures are not found under normal circumstances of transportation and use,ethyltriphenylfosfonium bromidewas considered non-flammable.
