Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Appearance / physical state / colour
Administrative data
Link to relevant study record(s)
- Endpoint:
- appearance / physical state / colour
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2017-02-06 until 2017-03-10
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- The study (OECD 471) was not specific to determine the appearance/physical state/colour for the substance and therefore has been allocated a reliability score of 2 as the observations performed are considered to be an accurate reflection of the physical state and colour of the test material.
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Visual evaluations were made on the physical state and colour in the description of materials section in a good quality OECD 471 (Ames test) study. The study was performed in line with GLP.
- GLP compliance:
- yes (incl. QA statement)
- Physical state at 20°C and 1013 hPa:
- solid
- Form:
- solid: crystalline
- Colour:
- white
- Substance type:
- organometallic
- Conclusions:
- The test material was described in an OECD 471 (Ames test) study as a white, crystalline solid.
- Executive summary:
Visual evaluations were made on the physical state and colour in the description of materials section in a good quality OECD 471 (Ames test) study. The study was performed in line with GLP. The test material was described as a white, crystalline solid.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
