Applicant's summary and conclusion
- Conclusions:
- The determination was performed in duplicate. In both determinations, a melting range was detected. The melting range was determined as 262 to 270°C (535.2 to 543.2 K). These values are the means of two independent determinations.
- Executive summary:
The validity criterion “difference between duplicate determinations” was met. The test item 5-Aminotetrazol Potassium showed a melting range, no melting point. It was noted, that a change in colour took place at 253 °C. No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
