What are quinoline intermediates used for?

They are used as building blocks for antimalarial, antimicrobial and kinase inhibitor APIs, as well as agrochemical and specialty chemical synthesis.

How do I choose between bromo and iodo quinoline intermediates?

Iodo derivatives are generally more reactive in cross-coupling, while bromo derivatives offer a good balance of reactivity and stability. The choice depends on your synthesis route.

Can I request a specification for a quinoline intermediate?

Yes. Send the CAS number and target quantity to our sales team to confirm purity, packaging and current availability.

Quinoline Intermediates for Pharmaceutical Synthesis

Why quinoline intermediates matter

The quinoline family supports antimalarial APIs such as Primaquine and Tafenoquine, fluoroquinolone antibiotics such as Ciprofloxacin and Levofloxacin, and quinoline-based antimicrobial and kinase inhibitor research.

Representative quinoline building blocks

5-Bromoquinoline (CAS 4964-71-0): brominated quinoline intermediate for antimalarial and antimicrobial quinoline API families
8-Iodoquinoline (CAS 1006-47-9): iodinated quinoline building block for functionalization and medicinal chemistry
6-Methoxy-8-aminoquinoline (CAS 90-52-8): methoxy-aminoquinoline intermediate used in antimalarial chemistry such as the Primaquine family

How to select a quinoline building block

Check the substitution position, halogen type and downstream target. Halogenated quinolines are usually selected for cross-coupling, while amino or methoxy derivatives are chosen when the functionality is already present in the target API.
