Description of key information
Appearance / physical state / colour:
The appearance of 7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one was observed to be Light yellow to yellow colored organic liquid compound.
Melting point/ Freezing point:
The Freezing point of 7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one was determined. No freezing was observed up to -5.02 °C. Hence, the freezing point was inferred to be less than -5.02 °C.
Boiling point:
The boiling point of 7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one was determined to be 123-125 °C.
Density:
The density of 7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one was determined to be 1.1300 g/cm3 at 25 °C.
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 7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one 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 substance 7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one at 25 deg C was 0.19 Pa.
Partition coefficient:
The octanol water partition coefficient i.e., log Pow of test chemical 7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one (CAS no. 4133 -34 -0) was estimated to be 1.99. On the basis of partition coefficient value it is conluded that this test chemical is hydrophilic in nature.
Water solubility:
The estimated water solubility of substance 7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one at 25 deg C was 1151 mg/l.
Surface tension:
Based on the prediction done by ACD labs, the surface tension for chemical 7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one was predicted to be 40.8 ± 3.0 dyne/cm.
Flash point:
The flash point of 7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one was estimated as 150.8 ± 21.4 °C.
Autoflammability:
7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one is not auto-flammable.
Flammability:
7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one 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 7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus 7-methoxy-1,2,3,4-tetrahydronaphthalen-2-one was considered non-flammable for chemical safety assessment.
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.
Additional information
