Chemical 1-methyl-3-phenylpropylamine physically appear as colorless liquid having amine like odor.

Melting point:

Freezing point of chemical 1-methyl-3-phenylpropylamine is determine to be less than -70 Deg C.

Boiling Point:

Boiling point of chemical 1-methyl-3-phenylpropylamine is determine in the range between 220 to 222 Deg C.

Density:

Density of chemical 1-methyl-3-phenylpropylamine is determine to be 0.928 g/cm3 at temperature 20 Deg C.

Particle size distribution:

The study does not need to be conducted because the substance is marketed or used in a non solid or granular form. Chemical 1-methyl-3-phenylpropylamine physically appear as liquid.

Vapour pressure:

The estimated vapour pressure of 1-methyl-3-phenylpropylamine at 25 deg C was 10.1458 Pa.

Partition coefficient:

Based on the available data from authoritative and modelling databases, the partition coefficient (log Pow) value of the substance1-methyl-3-phenylpropylaminewas estimated to be 2.12. Based on this value, chemical1-methyl-3-phenylpropylaminecan be considered to be hydrophilic in nature.

Water solubility:

The estimated water solubility of 1-methyl-3-phenylpropylamine at 25 deg C was 12050 mg/l.

Surface tension:

Surface tension of chemical 1-methyl-3-phenylpropylamine is determine to be 0.02725 N/m at temperature 143 Deg C.

Flash point:

Flash point of chemical 1-methyl-3-phenylpropylamine is determine to be 97.78 Deg C.

Auto flammability:

1-methyl-3-phenylpropylamine did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 1-methyl-3-phenylpropylamine is not auto-flammable.

Flammability:

1-methyl-3-phenylpropylamine 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 1-methyl-3-phenylpropylamine is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 1-methyl-3-phenylpropylamine 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 liquid.

pH:

pH of chemical 1-methyl-3-phenylpropylamine is determine to be 11.6 at temperature 20 Deg C & concentration 10 g/L.
