Physical Property Subsets

Ready-to-download subsets of ZINC filtered by physical properties are available below. All molecules in all of these subsets are purchasable. To go to the download page, click on the subset name. To browse sample compounds, click on the number of compounds. Three versions of subsets are available:
Standard:
For delivery in 0-10 weeks, including in-stock, make-on-demand and agent compounds
Clean:
Stricter filtering rules have been applied — e.g. aldehyes and thiols have been removed
In Stock:
For immediate delivery — typically less than 2 weeks
Boutique:
Boutique compounds — you should be willing to "pay any price". These are NOT included in standard, clean and in stock subsets, where the target price is $100 or less per sample
More about ZINC subsets is here. ZINC may be used free of charge for research by individuals and institutions. Whereas you are free to share the results of a ZINC search or a screen of molecules from ZINC, you may not redistribute major portions of ZINC without the express written permission of John Irwin.
