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.
Contact us if you have further questions or if you would like to send us a structure by email.
