Purity 99.6%
Physical state at 20°C and 1013 hPa:
solid
Key result
Form:
solid
Colour:
White colour based on visual observation. Munsell value of 9, a hue of neutral and chroma of 0.25 based on Munsell colour system
Odour:
other: Slight sulphur odor
Substance type:
organic

Determination of physical state, colour and odour was conducted at 23.5 degrees C.

Conclusions:
DPX-X1179 is a white coloured solid with slight sulphur odor.
The colour of DPX-X1179 based on the Munsell colour system had a Munsell value of 9, a hue of neutral and a chroma of 0.25.
Executive summary:

The appearance (physical state, colour, odor), was determined for DPX-X1179 as per the EPA OPPTS guidelines EPA OPPTS 830.6303 (Physical State), OPPTS 830.6304 (odour), OPPTS 830.6302 and ASTM Method D1535(colour).

DPX-X1179 was determined to be a white coloured solid with slight sulphur odor. The colour of DPX-X1179 based on the Munsell colour system was determined to have a Munsell value of 9, a hue of neutral and a chroma of 0.25.
