About building blocks and research compounds
Building blocks are small organic molecules with useful functional groups that chemists combine to make new compounds. This section covers heterocyclic, aromatic and aliphatic building blocks, boronic acids and esters, protected and unnatural amino acids, chiral building blocks, fluorinated building blocks, fragment compounds and screening compounds for drug, agrochemical and materials discovery.

CompoundList places an organic compound here when it has no known established industrial, pharmaceutical or consumer use, which is the case for most of the millions of catalogued research compounds. Many of these molecules are made by specialist suppliers in milligram to kilogram quantities, either from stock or on demand.
Discovery chemists value speed and reliable identity. When you request quotes, give the CAS number or the structure (you can draw or paste a SMILES string in structure search), the quantity, the minimum purity and the analytical data you need, usually 1H NMR and LC-MS. Ask whether the compound is in stock, where it ships from, and the lead time if it is made to order. For larger scale-up quantities, ask about the synthetic route, impurity profile and the ability to deliver repeat batches with consistent quality.

Frequently asked questions
Quick answers about buying building blocks and research compounds on CompoundList.
Why is a compound listed as a building block?
CompoundList places organic compounds here when they have no known established industrial, pharmaceutical or consumer use. Most catalogued research compounds fall into this group, sorted by structure.
Can I search by structure?
Yes. Use structure search to draw a molecule or paste a SMILES string, then search for exact matches, similar compounds or substructures.
What analytical data should I expect?
For research quantities, 1H NMR and LC-MS are standard, with purity usually at least 95 percent. For chiral compounds ask for enantiomeric excess, and for scale-up batches ask for a full certificate of analysis.
What does make-on-demand mean?
The supplier synthesises the compound after you order it, using a validated route. Lead times are usually a few weeks, and success rates and prices are confirmed in the quote.
