Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 269-929-9 | CAS number: 68391-11-7 The complex combination of polyalkylated pyridines derived from coal tar distillation or as high-boiling distillates approximately above 150°C (302°F) from the reaction of ammonia with acetaldehyde, formaldehyde or paraformaldehyde.

Description of key information
Determination of toxicity to microorganisms was carried out with 5-ethyl-2-methylpyridine (MEP, CAS no.: 104-90-5, EC no.: 203-250-0). The read-across between the UVCB substance and the model constituent is justified. A study equivalent or similar to EU Method C.11 and OECD Guideline 209 Activated Sludge, Respiration Inhibition Test was carried out. Pseudomonas putida was exposed to test item concentrations ranging from 7.9 to 16080 mg/L over a period of 18 hours. The NOEC value determined was 38.8 mg/L.
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 38.8 mg/L
Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
