- Endpoint:
- appearance / physical state / colour
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- FROM 18-FEB-2010 to 13-APR-2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Remarks:
- The description of the substance comes from an experimental study report on flammability, conducted in accordance with Good Laboratory Practices. The substance is adequately defined (with certificate of analysis). No specific test guideline is required.
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- Visual inspection
- GLP compliance:
- yes (incl. QA statement)
- Physical state at 20°C and 1013 hPa:
- solid
- Form:
- flakes
- Colour:
- Brown shavings
- Substance type:
- organic
- Conclusions:
- Catechol is an organic solid substance, appearing under the form of brown flakes at ambient temperature and pressure.
- Executive summary:
The substance, catechol, was tested for flammability under GLP. In this context, the appearance of the sample was described, indicating that catechol is a solid substance appearing under the form of brown flakes.
- Endpoint:
- appearance / physical state / colour
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- data from handbook or collection of data
- Remarks:
- Data comes from peer-reviewed handbooks cited among "reference books containing peer-reviewed physico-chemical data" in the ECHA guidance document on information requirements and chemical safety assessment (R.7a).
- Reason / purpose for cross-reference:
- reference to same study

Additional information
An experimental study of reliability 1 according to Klimisch, dealing with another endpoint but reporting description of the substance, was selected as a key study. Supporting data coming from peer-reviewed handbooks were consistent with the above study, with further information on the colour and the odour.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
