- GLP compliance:
- no
Test material
- Reference substance name:
- 2-chlorobenzothiazole
- EC Number:
- 210-415-0
- EC Name:
- 2-chlorobenzothiazole
- Cas Number:
- 615-20-3
- Molecular formula:

- 2-chloro-1,3-benzothiazole
- Details on test material:
- purity >99 % w/w
Constituent 1
Study design
- Analytical monitoring:
- yes
- Details on sampling:
- Samples for analysis were taken at 6 or 7 sampling intervals between 0 and 72 hours after start of incubation
- Buffers:
- Media (including algae nutrient medium containing trace amounts of inorganic components, e.g. heavy metals) see below
An amount of 2-Chloro-1,3-benzothiazole was dissolved in buffer solution (pH 7 or pH 9) or in nutrient medium. The final initial concentration of the test substance in the different test solutions was 20 mg/l. - Estimation method (if used):
- Test solutions exposed to different environmental conditions over a period of three days were analysed for the content of 2-Chloro-1,3-benzothiazole in order to examine the stability of the substance in aqueous test solutions.

Results and discussion
- Preliminary study:
- in the dark (personal communication)
- Transformation products:
- not measured
- Details on results:
- Under all test conditions and at all sampling time points, the concentration of the substance was 20 mg/L
Any other information on results incl. tables
As there was no decrease of concentration observed in the media, the substance is stable under the experimental conditions
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- Under the test conditions, no degradation of 2-chloro-1,3-benzothiazole was observed.
- Executive summary:
In a test designed to evaluate the stability of the substance in dilute aquatic media in the light and in the presence of air, the concentration of the substance did not decrease during three days at 50 °C in buffer at pH 7, in buffer at pH 9, and in a simulated environmental medium (algal nutrient medium containing traces of heavy metals, pH 9 after 3 d).
