Hydroquinone diethyl ether (1,4-diethoxybenzene) is a soft, sweet-floral aromachemical with a hawthorn-like character reminiscent of anethole and hay. It has a powdery, slightly anisic facet and a mild coumarinic warmth, often used to add a natural blossom-honey nuance to floral and fougere accords.AI · claude-opus-4-7
