Problems Loading the Applet

Help Center

There can be several reasons why the applet for drawing chemical structures did not load. The most common are:

  • Problem nr. 1
          Problem description: Internet security settings at your company block Java applets.
          Solutions: Visit the Java test page to verify if you have a recent version of Java installed on your computer. If the test fails, you can inform your network administrator. After reviewing our website and determining that the applet is safe, the administrator most likely will enable its use.

          Solution: Close the browser. Open a browser and reload the page with the applet.

          Solution: Update Java virtual machine to the latest version.

Still unable to use the structure drawing applet?

You have two search options in the MolPort database:

  • Text search. Use the search box at the top right corner of the page. Unfortunately, we don't have names or CAS numbers for all of the molecules in our database. It is possible, that we have a supplier for your molecule in our database but it can be found only by using the structure search option.
  • Import search. After you register and login, you will be able to submit the structure in a file saved in MDL SDfile format (.sdf). You can submit up to 20 structures in one file.
