Homoquinoline (methylquinoline) is a pungent, dry aromatic material with a strongly animalic-leathery character reminiscent of quinoline itself but softer and slightly sweeter. It smells of tobacco, tar, and dusty old leather with an earthy, faintly medicinal undertone. Powerful at trace levels — overdose reads as smoky and animalic-fecal.AI · claude-opus-4-7
