Surface tension:
In accordance with column 2 of Annex VII of the REACH regulation, the study need only be conducted if surface activity is a desired property of the chemical. 3-(diethylamino)-7 -imino-7H-[1]benzopyrano[3',2':3,4]pyrido[1,2 -a]benzimidazole-6 -carbonitrile (CAS no. 52372 -39 -1) is used as a dye. For this use, surface activity is not an important property. Hence this study was considered for waiver.
Flash point:
The flash point of 3-(diethylamino)-7-imino-7H-chromeno[3',2':3,4]pyrido[1,2-a]benzimidazole-6-carbonitrile is determine to be greater than 200°C at 980.7 hPa.
Auto flammability:
3-(diethylamino)-7-imino-7H-chromeno[3',2':3,4]pyrido[1,2 -a]benzimidazole-6 -carbonitrile did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 3 -(diethylamino)-7 -imino-7H-chromeno[3',2':3,4]pyrido[1,2 -a]benzimidazole-6 -carbonitrile is not auto-flammable.
Flammability:
3-(diethylamino)-7 -imino-7H-chromeno[3',2':3,4]pyrido[1,2 -a]benzimidazole-6 -carbonitrile 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 3 -(diethylamino)-7 -imino-7H-chromeno[3',2':3,4]pyrido[1,2 -a]benzimidazole-6 -carbonitrile is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 3 -(diethylamino)-7 -imino-7H-chromeno[3',2':3,4]pyrido[1,2 -a]benzimidazole-6 -carbonitrile was considered non-flammable.
Explosiveness:
The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties.
Oxidizing properties:
The study does not need to be conducted because the substance is a solid.
