(pyrrolyl-2)-propan-1,2-dione

(pyrrolyl-2)-propan-1,2-dione is an organic heterocyclic diketone containing a pyrrole ring substituted at the 2-position with a propane-1,2-dione moiety. The compound appears as a defined chemical entity used primarily for research or informational purposes rather than commercial flavoring or fragrance applications. It is noted for a bitter taste with roasted peanut sensory characteristics. Synonyms include 1-(2-pyrrolyl)propane-1,2-dione and 1-(2-pyrrolyl)-1,2-propanedione. Its chemical structure and properties can be further explored through controlled vocabulary platforms such as PubChem. This compound is typically synthesized or isolated for investigative studies rather than from natural sources or widespread industrial procurement.

(pyrrolyl-2)-propan-1,2-dione is not known to occur naturally in significant biological contexts and is primarily of interest in chemical research. Its strong bitter and roasted peanut flavor profile has limited practical application, as it is not used in food flavoring or fragrance products. Regulatory guidance, such as from FEMA (US), indicates that this compound is not authorized for flavor or fragrance use. Its presence is mainly considered in the context of chemical information or experimental studies rather than commercial formulation or product development. This restricts its applicability to academic, analytical, or informational domains.

This compound's molecular structure, consisting of a pyrrole ring linked to a propane-1,2-dione group, influences its chemical reactivity and sensory perception. The diketone functional groups confer potential electrophilic character, which may affect stability and interactions in formulations. Its bitter aromatic notes stem from the heterocyclic and diketone moieties that interact with sensory receptors. The molecular framework suggests moderate polarity and potential solubility in organic solvents but limited volatility, which impacts its behavior in mixtures. These properties guide its limited usage, primarily restricting it to controlled experimental contexts rather than widespread flavor or fragrance application.
