6-Isopropylquinoline from TCI (product code I0529, CAS 135-79-5) is a quinoline derivative with an isopropyl group at the 6-position of its aromatic ring system. Quinoline is a nitrogen-containing aromatic heterocycle made of a benzene ring fused to a pyridine ring. This framework is the basis of many drugs, dyes, ligands, and fragrance materials. In the laboratory, 6-isopropylquinoline is used as a heterocyclic building block for organic synthesis and medicinal chemistry. It also serves as a reference compound in structure–activity studies of quinoline derivatives.

Researchers choose this compound because it pairs the basic nitrogen atom of the quinoline ring with a branched alkyl substituent that makes the molecule more lipophilic. The nitrogen atom can act as a metal coordination site, a protonation site, or the point where salts and N-oxides form. The isopropyl group affects solubility, steric bulk, and how the molecule interacts with biological targets. This combination is useful when researchers want to vary substituents on the quinoline framework systematically. Alkylated quinoline derivatives like this one are also known in fragrance chemistry.

In Indonesia, 6-isopropylquinoline is used mainly by synthetic organic chemistry and medicinal chemistry laboratories at universities, research institutes, and industrial research and development units. These groups typically use it in small-scale exploratory synthesis, in building compound libraries based on the quinoline scaffold, and in comparative studies where the 6-isopropyl substituent is set against other substitution patterns. Supplying it under TCI's catalogue code makes it easier for laboratories to keep their reagent sourcing consistent and well documented from one project to the next.

  • Heterocyclic building block in organic synthesis, where the quinoline core provides a ready-made fused nitrogen heterocycle that can be carried forward into larger and more complex target molecules.
  • Medicinal chemistry scaffold exploration, because the quinoline framework is common in drug compounds and the 6-isopropyl group adds lipophilicity and steric bulk that can be compared directly against other analogues.
  • Structure–activity relationship studies of quinoline derivatives, where this compound acts as a defined reference point for seeing how a branched alkyl substituent at the 6-position changes the observed activity.
  • Ligand and coordination chemistry research, since the basic ring nitrogen can bind metal centres while the isopropyl substituent changes the steric and solubility profile of the resulting complexes.
  • Preparation of salts and N-oxide derivatives, where the protonatable quinoline nitrogen allows straightforward conversion into related species that differ in polarity, solubility, and reactivity for further study.

Storage keep tightly closed in a cool, dry, well-ventilated place; follow the supplier's Safety Data Sheet

Store 6-isopropylquinoline in its original tightly sealed container in a cool, dry, well-ventilated area, away from direct sunlight, heat sources, and strong oxidising agents. If you transfer the material, use clean, compatible glass containers with secure closures and clear labels showing the product name, CAS number, and date opened. Handle the compound in a fume hood and wear standard personal protective equipment: a lab coat, safety glasses, and chemical-resistant gloves. Avoid breathing vapours and avoid contact with skin and eyes. Before use, read the TCI Safety Data Sheet for specific hazards, first-aid measures, and storage requirements. Dispose of waste according to institutional and local regulations.
