Handbook data: The data in the handbook have been derived from many sources, including both the primary literature and evaluated compilations. The Handbook of Data on Organic Compounds, Third Edition and the Chapman & Hall/CRC Combined Chemical Dictionary were important sources. Other useful compilations of physical property data for organic compounds are listed in the references below. Many boiling point values (and some melting point and density values) were taken from recent physical chemistry literature dealing with fluid properties. Where conflicts were found, the value deemed most reliable was chosen.
1. Laboratory reagent lists, e.g., the ACS Reagent Chemicals volume (Ref. 1)
2. The DIPPR list of industrially important compounds (Ref. 2) and the (much larger) TSCA Inventory of chemicals used in commerce
3. The Hazardous Substance Data Bank (Ref. 3)
4. The UNEP list of Persistent Organic Pollutants (Ref. 4)
5. Chemicals on Reporting Rules (CORR), a database of about 7500 regulated compounds prepared by the Environmental Protection Agency (Ref. 5)
6. The EPA Integrated Risk Information System (IRIS), a database of human health effects of exposure to chemicals in the environment (Ref. 6)
7. Compendia of chemicals of biochemical or medical importance, such as The Merck Index (Ref. 10)

Description of key information

The density of 1,3-diiodopropane is reported as 2.5612 g/cm³, determined at 25 °C. This value is in good agreement with values from a supporting study (Grzeskowiak, 1960) showing the rel. density (to water at 4 °C) being 2.5742 at 20 °C, 2.5360 at 40 °C, 2.4981 at 60 °C and 2.4510 at 85 °C; another supporting study reported a relative density at 18 °C to be 2.532 (Lichtenberger, 1961).

Key value for chemical safety assessment

Relative density at 20C:
2.56
