Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

The test item was tested using a nominal concentration of 40 mg organic carbon/L in test medium following OECD 301A and EU-Guideline C.4-A.
Aniline was chosen as reference item.
Activated sludge was used as inoculum (concentration in the test 25.1 mg dry matter/L). The test was left running for 28 days.
All validity criteria were met. Degradation of the reference item was 94.7 % after three days.
10-day-window: not detected
degradation at the end of the test: none
Therefore 1 H-Tetrazol-5-amine-, N-1H-tetrazol-5-yl-, monoammonium salt is considered as not readily biodegradable following OECD 301A/EU C.4-A.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Data obtained from a guideline study according to OECD guideline 301A and therefore considered reliable without restrictions.
