Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

EC number: 204-427-5 | CAS number: 120-80-9
Bioaccumulation: aquatic / sediment
Administrative data
Link to relevant study record(s)
- Endpoint:
- bioaccumulation in aquatic species: fish
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance has a low potential for bioaccumulation based on log Kow <=3

Description of key information
Based on the partition coefficient values reported in the literature which ranges from 0.84 to 1.03, Catechol has a low potential for bioaccumulation.
Key value for chemical safety assessment
Additional information
As no reliable data is available on the bioaccumulation potential of catechol, the assessment has to be performed based on data on n-octanol/water partition coefficient. Among the available results, one experimental study, divided in two publications (Garst & Wilson 1984, Garst 1984), was selected as a key study and give coefficient partition values ranging from 0.88 to 0.95. Other experimental and calculated results were selected as supporting studies, giving values comprised between 0.84 and 1.03. An average of all the Klimisch 2 data was calculated to obtain the key value of 0.93 used for chemical safety assessment.
Based on all the above mentioned data, catechol has a low potential for bioaccumulation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
