Description of key information

Appearance / physical state / colour:

On the basis of physical observation and using the sense of smell, the Reaction mass of 3H-​Indolium, 2-​[[2-​(4-​methoxyphenyl)​-​2-​methylhydrazinyliden​e]​methyl]​-​1,​3,​3-​trimethyl-​ & acetate was observed to be a yellow liquid organic compound.

Melting point/ Freezing point:

The Freezing point of Reaction mass of 3H-​Indolium, 2-​[[2-​(4-​methoxyphenyl)​-​2-​methylhydrazinyliden​e]​methyl]​-​1,​3,​3-​trimethyl-​ & acetate was determined using freezing temperature method. No freezing was observed up to -10.21 °C.

Boiling point:

The mean boiling point of Reaction mass of 3H-​Indolium, 2-​[[2-​(4-​methoxyphenyl)​-​2-​methylhydrazinyliden​e]​methyl]​-​1,​3,​3-​trimethyl-​ & acetate was119°C at 971.7 hPa.

Density:

The mean density of Reaction mass of 3H-​Indolium, 2-​[[2-​(4-​methoxyphenyl)​-​2-​methylhydrazinyliden​e]​methyl]​-​1,​3,​3-​trimethyl-​ & acetate was found to be 1.111 g/cm³ at 20°C and 975.0 hPa.

Particle size distribution (Granulometry):

In accordance with column 2 of Annex VII of the REAcH regulation this end point was considered for waiver since the chemical Reaction mass of 3H-​Indolium, 2-​[[2-​(4-​methoxyphenyl)​-​2-​methylhydrazinyliden​e]​methyl]​-​1,​3,​3-​trimethyl-​ & acetate is a liquid and is expected to be marketed or used in a non solid or granular form.

Vapour pressure:

The estimated vapour pressure of the test substance Reaction mass of 3H-​Indolium, 2-​[[2-​(4-​methoxyphenyl)​-​2-​methylhydrazinyliden​e]​methyl]​-​1,​3,​3-​trimethyl-​ & acetate at 25deg C was 6.84E-12 Pa (5.13E-14 mm Hg).

Partition coefficient:

By using KOWWIN Program (v1.68) of Estimation Program Interface (EPI suite, 2018) the octanol water partition coefficent (log Pow) of chemical Reaction mass of 3H-​Indolium, 2-​[[2-​(4-​methoxyphenyl)​-​2-​methylhydrazinyliden​e]​methyl]​-​1,​3,​3-​trimethyl-​ & acetate was estimated to be 0.96 dimensionless at temparature 25oC.

Autoflammability :

Reaction mass of 3H-​Indolium, 2-​[[2-​(4-​methoxyphenyl)​-​2-​methylhydrazinyliden​e]​methyl]​-​1,​3,​3-​trimethyl-​ & acetate did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 2-[[(4-methoxyphenyl)methylhydrazono]methyl]-1,3,3-trimethyl-3H-indolium acetate is not auto-flammable.

Flammability:

Reaction mass of 3H-​Indolium, 2-​[[2-​(4-​methoxyphenyl)​-​2-​methylhydrazinyliden​e]​methyl]​-​1,​3,​3-​trimethyl-​ & acetate 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 Reaction mass of 3H-​Indolium, 2-​[[2-​(4-​methoxyphenyl)​-​2-​methylhydrazinyliden​e]​methyl]​-​1,​3,​3-​trimethyl-​ & acetate is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Reaction mass of 3H-​Indolium, 2-​[[2-​(4-​methoxyphenyl)​-​2-​methylhydrazinyliden​e]​methyl]​-​1,​3,​3-​trimethyl-​ & acetate 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.

Oxidising properties:

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidizing properties and hence the classification procedure does not need to be applied.
