Using this page, you can contribute a molecule to OdorSpace. We cannot promise you that
we will add your molecule to OdorSpace, but we will try. Once we do, it will become public
information, and by contributing, you agree to that.

Molecule information
for each molecule please include a rating of perceived intensity at 100% concentration. 
Or you can upload a csv list of the molecules using the CSV file field below.
CID perceived intensity
The rating of perceived intensity at 100% concentration.
The rating of perceived intensity at 100% concentration.
You can add a list of molecules, include them in a csv with columns for CID and intensity.
One file only.

Allowed types: csv.

*Component perceived intensity

Here you enter the perceived intensity of the component. You can get a sense of the scale we use by looking at the default values suggested by for recommended smelling dilution. Here please rate your component for perceived intensity. This rating does not need to be very accurate, but rather a rough estimation will do. To calibrate your estimation, consider the following "standards":

Methyl isoeugenol (CID: 7128) at 100% = Very Weak (between 1 and 15)

PEA (CID: 6054) at 100% or Beta-ionone (CID: 638014) at 100% = Weak (between 16 and 36)

para-cresyl isobutyrate (CID: 7685) at 100% = Intermediate (between 37 and 61)

Isovaleric acid (CID: 10430) at 1% or Eugenol (CID: 3314) at 10% = Strong (between 62 and 85)

Citral (CID: 638011) at 100% = Very Strong (between 86 and 100)
