On the basis of this value, test substance 1,4-phenylene bis[(4-phenoxyphenyl)-methanone] can be considered to be hydrophobic in nature.

Water solubility:

The water solubility determination of test item [4 -(4 -phenoxybenzoyl)phenyl](4 -phenoxyphenyl)methanone (CAS No. 54299 -

17 -1) was done as per the OECD guideline 105 by spectrophotometric analytical method as per OECD 101. The solubility of

([4 -(4 -phenoxybenzoyl)phenyl](4 -phenoxyphenyl)methanone of CAS No: 54299 -17 -1 )in water was determine to be 0.56265 mg/L

at 25°C.

From this solubility value it is concluded that chemical is slightly soluble in water.

Surface tension:

The study does not need to be conducted because water solubility is below 1 mg/L at 20°C.

Flash point:

The flash point determination of Test item [4-(4-phenoxybenzoyl)phenyl](4-phenoxyphenyl)methanone (CAS No. 54299-17-1 )was done. The method was closed cup method using Pensky-Martens Flash Point Apparatus. The flash point of the test item was determine to be 205.6°C at 966.7 hPa.

Auto flammability:

[4-(4-phenoxybenzoyl)phenyl](4-phenoxyphenyl)methanone did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that [4-(4-phenoxybenzoyl)phenyl](4-phenoxyphenyl)methanone is not auto-flammable.

Flammability:

[4-(4-phenoxybenzoyl)phenyl](4-phenoxyphenyl)methanone 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 [4 -(4 -phenoxybenzoyl)phenyl](4 -phenoxyphenyl)methanone is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus [4 -(4 -phenoxybenzoyl)phenyl](4 -phenoxyphenyl)methanone 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.

pH:

The pH determination of test item [4-(4-phenoxybenzoyl)phenyl](4-phenoxyphenyl)methanone (CAS No 54299-17-1) was done following OECD guideline 122. pH of 1% w/v dispersion was measured with the help of pH meter and it was observed to be 5.75 at 25 °C.
