The different quinolines:

• Pyralone is a refined version of butylquinoline, which offers a more aromatic and tobacco-like scent. It has less of the dry, earthy character compared to secondary butyl quinoline. Pyralone is often used in chypre, fougère and tobacco accords for its leathery, green and woody notes.
• Butyl quinoline Secondary: This compound has a green, metallic and leathery scent, with a bitter green quality reminiscent of nettles and chrysanthemum stems. It is often used in traditional chypre and fougère perfumes, to enhance green and mossy notes, and has a more pronounced dry and earthy character than Pyralone.
• Iso-butyl quinoline has a bitter green, metallic and leathery scent with an animalic and earthy quality. It is often used in traditional chypre and fougère perfumes to enhance bitter, green notes and blends well with vetiver, moss and patchouli.
• Isobutyl quinoline-2: This isomer provides a distinctive leathery and animalic scent, with a slightly different structural arrangement than isobutyl quinoline. It is often used in leather and mossy accords to add depth and complexity.
