Rich Apodaca, the author of the Depth-First website, is on the hunt for free databases. I’ll let Rich’s own words speak for his quest “Here’s the idea: if you run a free database or other online chemistry service and would like to promote it, post a comment to this article containing a link and brief description of what makes your service different/useful. If you’ve used a free chemistry database, feel free to provide your thoughts on it. If there’s a free database you wish existed but doesn’t yet, feel free to write about that.”

I’m posting this to help direct people with an interest in free databases, and potentially WITH a free database to Rich’s site to provide exposure for his list. Redirect mode….mosey on over to Depth-First and let Rich know your ideas…it will provide good service to the community.

Stumble it!

    Free databases are hard to come by, and when one is found, it usually is too small or unreliable to be useful. However, there are two notable databases that I use, PubChem and SDBS. PubChem, hosted by NCBI (, contains millions of molecules, structures and information free to download. Although I see Rich already knows of PubChem. One database I didn’t see him mention is SDBS, which contains over 100,000 spectra free to search (

    As for free chemical applications, I have been creating and distributing educational tools through my site At the moment iChemLabs hosts 1H and 13C NMR virtual simulators and MolGrabber, a utility for producing molecule files and graphics (using PubChem). These applications are being used at universities across the country and I am looking for online means to reach students and interested scientists.

    I hope this post helps you and Rich, and let me know if you want to know more about what I do.
