No information on the primary source of this
data or the methods used is available. However, this information is
taken from a reliable government source and is therefore considered to
be suitable for use as a key study.
The boiling point of DCPD is 172.2 °C at 760
mmHg as cited in the NIOSH handbook.
The boiling point of high purity DCPD is 172.2°C. The boiling point of commercial DCPD (>80%) is 80-190°C.
The Pocket Guide presents
key information and data from the US Department of Health and Human
Services and as such is a reliable governmental source of information
and is considered a suitable key study source for this endpoint (NIOSH
2005). This is supported by a boiling point of between 170°C and
172°C from the WHO ICSC (2005). The test substance decomposes at this
temperature range. No information on the primary source of the data or
the methods used is available. However, this information is taken from a
reliable peer reviewed database and so can be considered reliable and
suitable for use for this endpoint.
The boiling point of commercial DCPD was
taken from proprietary data (DOW 2016). There is no information on the
GLP status of the study or the methods used but the results are taken
from company specific datasheets and are considered to be suitable for
use for this endpoint.
