Quality is important

The design of screening libraries and the development of predictive drug discovery models all start with a high quality database. Chemical correctness is crucial because mis-drawn and imperfectly defined structures result in incorrect models, misleading predictions and inconsistent hits. Problematic structures should therefore be eliminated at the earliest possible stage from a drug discovery pipeline.


Why the mcule database is of high quality

The mcule database is curated by MAC (mcule advanced curation) that involves a rigorous molecule registration system based on more than 80 structural checks, standardization, preparation and correction steps. MAC guarantees high quality search results and avoids common errors arising from mis-drawn and incorrect structures that can critically affect the quality of computational calculations and the efficiency of experimental results.

Purchase compounds from mcule

The high quality mcule database ensures high quality hits for your research projects. We keep our database up-to-date. Stock availability for more than 90% of our products is instantly or daily updated. Our procurement service delivers compounds to almost anywhere in the world quickly and efficiently. No matter how many suppliers you have selected compounds from, we deliver them to your door as a single package. Single website, single contact, single package.

Our goal is to incorporate all purchasable compounds into the mcule database. Please send the name and website of your favourite chemical supplier that you would like to be added to the mcule high quality database.


How to purchase the selected compounds

After signing into your mcule account, paste or upload a list of mcule IDs into our Find Chemicals interface and click on "Search". Then click on the orange "Quote" button, fill out the quote form and submit your quote request. If you have access to Instant Quote, we will provide you with a quote on-the-fly, if not, you can choose Next-Day Quote and we will get back with a quotation in 24-48 hours.

Challenge us! If you have hits from other databases, you can upload them in SMILES, InChI or SDF formats, and see how many of them are purchasable from mcule.

Download or filter by supplier data

If you need more information such as stock availability and supplier names and IDs, subscribe to one of our plans.

Subscribed users can download supplier data for all purchasable compounds including supplier name and ID, catalog name, purity and stock availability. Moreover, you get access to the Product filter that conveniently selects any subset of the mcule database based on your criteria. Use the Product filter to design your own screening library!
