Remarks on result:
other: Reported as 1.129 ± 0.005 g/mL
Conclusions:
The density of 1,1'-isophthaloylbis(2-methylaziridine) was measured as 1.129 g/cm3 at 25.7 °C using a pycnometer.
Executive summary:

The density of 1,1'-isophthaloylbis(2-methylaziridine) was measured as 1.129 g/cm3 at 25.7 °C. Duplicate measurements were taken with a calibrated pycnometer at 25.7 °C and averaged. The study was comparable to a guideline study but was not conducted under GLP; therefore the results are considered reliable with restrictions.

Remarks on result:
other: temperature not reported
Conclusions:
1,1'-Isophthaloylbis(2-methylaziridine) has a relative density of 1.1.
Executive summary:

1,1'-Isophthaloylbis(2-methylaziridine) has a relative density of 1.1. Only the result was reported on the SDS and no information about the method used was provided; therefore the reliability of the data is not assignable.

Description of key information

The density of 1,1'-isophthaloylbis(2-methylaziridine) was measured as 1.129 g/cm3 at 25.7 °C using a pycnometer.

Key value for chemical safety assessment

Additional information

In the key study, duplicate measurements were taken with a calibrated pycnometer at 25.7 °C and averaged. The study was comparable to a guideline study but was not conducted under GLP; therefore the results are considered reliable with restrictions. In a supporting study, a relative density of 1.1 was reported. Only the result was reported on the SDS and no information about the method used was provided; therefore the reliability of the data is not assignable.
