Endpoint:
appearance / physical state / colour
Type of information:
other: visual observation
Adequacy of study:
key study
Study period:
2011
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: no guideline followed but evaluation was performed by trained personnel at a GLP facility
Qualifier:
no guideline followed
Principles of method if other than guideline:
Visual evaluation of the substance upon arrival at GLP test facility performed by trained personnel.

Visual observation during the particle size test (see 4.5). The sample was observed directly and under a microscope with 100x and 400x magnification. Temperature and pressure: ambient conditions.

GLP compliance:
yes (incl. certificate)
Remarks:
observation during particle size study
Physical state at 20°C and 1013 hPa:
solid
Form:
powder
Colour:
white to off-white
Odour:
other: not determined
Substance type:
organic
Conclusions:
FDCA is a white to off-white powder under ambient conditions. It is made up of agglomerated small particles.
