2-Methylquinoline

2-Methylquinoline (CAS 91-63-4 ), commercially recognized as Quinaldine, is a nitrogen-containing heterocyclic compound used across pharmaceutical synthesis, dye manufacturing, and specialty chemical production.

It functions primarily as a building block and intermediate, enabling the construction of more complex active molecules and functional materials. In pharmaceutical manufacturing, it serves as a key synthetic intermediate.

This includes the production of antimalarial compounds, including quinine derivatives, and other bioactive heterocyclic APIs. Polymer and plastics producers use it as a stabilizer and antioxidant precursor.

It is particularly useful in formulations requiring protection against thermal degradation. In dye and pigment chemistry, it contributes to the synthesis of quinoline yellow and related colorants.

These colorants are used in food-contact and industrial coating applications. Flavor and fragrance formulators incorporate it at controlled concentrations where its characteristic quinoline note is required.

2-Methylquinoline is supplied as a liquid at ambient conditions, typically offered in technical and high-purity grades suited to pharmaceutical intermediate and specialty chemical applications.

Standard purity levels of 98% and above are commonly available for research and industrial procurement. Packaging ranges from small laboratory quantities through to drum volumes for global shipping.
