- other: 2-[7-(diethylamino)-2-oxo-2H-1-benzopyran-3-yl)-1,3-dimethyl-1H-benzimidazolium chlorine (CAS No. 29556-33-0) not ignited when the flame of bunsen burner having temperature of approximately 950°C was brought in contact with it.
Applicant's summary and conclusion
- Interpretation of results:
- other: non flammable
- Conclusions:
- 2-[7-(diethylamino)-2-oxo-2H-1-benzopyran-3-yl)-1,3-dimethyl-1H-benzimidazolium chlorine (CAS No. 29556-33-0) does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that 2-[7-(diethylamino)-2-oxo-2H-1-benzopyran-3-yl)-1,3-dimethyl-1H-benzimidazolium chlorine (CAS No. 29556-33-0) is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 2-[7-(diethylamino)-2-oxo-2H-1-benzopyran-3-yl)-1,3-dimethyl-1H-benzimidazolium chlorine (CAS No. 29556-33-0) was considered non-flammable for chemical safety assessment.
- Executive summary:
2-[7-(diethylamino)-2-oxo-2H-1-benzopyran-3-yl)-1,3-dimethyl-1H-benzimidazolium chlorine (CAS No. 29556-33-0) does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that 2-[7-(diethylamino)-2-oxo-2H-1-benzopyran-3-yl)-1,3-dimethyl-1H-benzimidazolium chlorine (CAS No. 29556-33-0) is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 2-[7-(diethylamino)-2-oxo-2H-1-benzopyran-3-yl)-1,3-dimethyl-1H-benzimidazolium chlorine (CAS No. 29556-33-0) was considered non-flammable for chemical safety assessment.
