How it behaves

Olfactory profile

Descriptors
sweet

Extremely powerful, aggressive sulfurous odor reminiscent of raw garlic, onion, and rotting alliums. Intensely diffusive and repellent in isolation — used only at trace parts-per-billion levels where it contributes savory, roasted-allium or coffee-like nuances.AI · claude-opus-4-7
