Is there a comprehensive chemical odor threshold database?

[n8cole]

I work in air pollution control and am occasionally responsible for designing equipment to neutralize odors. While I can often find the odor threshold of a target chemical using resources like CAMEO or various chemical databases, I’m looking for a more comprehensive and dedicated database that specifically focuses on odor-related properties.

odor-related properties.

can you describe what you mean?

a good source for odor threshold is PubChem, e.g.

Hydrogen Sulfide

Hydrogen Sulfide | H2S | CID 402 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.

pubchem.ncbi.nlm.nih.gov

Specifically, I am looking for a database of the chemicals odor threshold - at what concentration is the chemical olfactorily undetectable.

PubChem is good, and so is Cameo if the USCG CHRIS Code is published. But I am hoping for the existence of a much larger database.

I understand that this is a shoot in the dark and it's unlikely that something like that exists. But this site has surprised me before.

Hi,
Some data about acrylic esters. Those materials, in particular EA, have a strong odor at very low concentration.

The 13 references for H2S under the PubChem link is not large enough? How many do you need? If few, then what is wrong with these?

if USCG CHRIS Code is published

Note that CAS# is more popular.

Still waiting for what properties you mean.
