 What are Material Properties?

Scale-up Suite contains a Materials System with properties information on a wide range of substances related to organic synthesis and bioprocessing.  Where possible, we include common synonyms and friendly names for materials, so that our system is easy to use. The principal sources of our material properties are listed at the end of this page.  We have curated these properties carefully over two decades.

The Properties item in the Dynochem Excel ribbon provides quick and easy interactive access to this materials information.  Similar data may be retrieved into Excel formulae using our DC_functions, also  available from the ribbon.  The materials system can also be queried from external programs through an API by writing custom code; contact for more information and to discuss licensing if you wish to do this.

 What Properties are available?

Materials with greatest coverage in our system are solvents.  Less data are generally available for reagents, bases and heat transfer fluids.  Where possible and the data are available, our properties are temperature-dependent.  The full list of properties for pure components is:

For mixtures, the following parameters and calculation methods are available in DC_functions or utilities, which leverage pure component information from the materials system:

VLE BIPs Group contribution Solubility
UNIQUAC UNIFAC Modified Solute activity
Solvent activity UNIFAC LLE Van't Hoff
4-parameter models (T,x)
Hydrogen, Oxygen, Nitrogen, Carbon Dioxide

 Note that access to material properties for your own proprietary components can be streamlined for users through our Materials Data Service system.

 How can I use it?

For basic everyday usage:

  1. Open the Properties task pane using the Properties item in the ribbon
  2. Type the first few letters of the component name of interest, e.g. "EtOH"
  3. Review the list of properties available in the lower frame
  4. Optionally type a few letters of the name of a property to filter the results, e.g. "den" for density
  5. Optionally enter a temperature at which the properties should be displayed
  6. Optionally write values back to the current worksheet (at the cursor position) by clicking on either Write with Details or Write Value buttons


For advanced usage, construct queries using a simple query language:

  1. Open the Properties task pane
  2. Start typing a query using the equals sign "="
  3. Auto-prompts will appear, helping you to complete the query and explaining the meanings of each available property code
  4. Add further queries using auto-prompts and click Finish when done
  5. Optionally use the Filter button on the right to select which material categories are shown
  6. Optionally change the source of the Properties information using the cylinder button (note that changing the source will change the list of properties available)


We source many pure component physical properties that are temperature-dependent (e.g. liquid density, liquid heat capacity) and also a range of temperature-independent properties from the peer-reviewed DIPPR Database. We source phase equilibrium parameters from the Dortmund Data Bank (DDB) and where gaps exist in their data, we estimate parameters using the modified UNIFAC model. We collate a range of other properties of interest to the user community from various source including ACS and check values against measured or published data where possible.  We source excipients information from the FDA website.

For further details about the ACS solvent selection guide, visit the following ACS link. The guide assigns a score from 1 to 10 for each solvent under the respective categories, with a score of 10 being of most concern and a score of 1 suggesting few issues.  For the ACS scores, 1=good and 10=bad.

For further details about the GSK solvent selection guide, visit the following link. Each solvent is scored from 1 (red) to 10 (green) to give a relative ranking for every solvent in the guide in each category, where the score is based on data or a physical observable property.  Supplementary information is available here. In the GSK scores, 1=bad and 10=good.
