(N-methyl-pyrryl-2)-methylthiol acetate

(N-methyl-pyrryl-2)-methylthiol acetate is a synthetic organosulfur chemical characterized by a distinct metallic and burnt flavor profile. It belongs to the class of thioacetate derivatives containing a methylated pyrrole ring linked to a methylthiol acetate group. Synonyms include (N-methyl-2-pyrryl)methyl thiol acetate and various similarly hyphenated forms. This compound is not commonly found in nature but is of interest in flavor chemistry research due to its potent, sulfurous sensory qualities. Its molecular structure and properties are documented in public chemical databases such as PubChem. The compound is generally synthesized for analytical or experimental investigations rather than commercial fragrance or flavor formulations.

(N-methyl-pyrryl-2)-methylthiol acetate does not occur naturally in significant concentrations and is not employed in commercial fragrance or flavor products. Its primary application is informational, serving as a reference molecule in sensory and chemical studies investigating sulfur-containing flavor compounds. Usage guidelines as per safety assessments recommend no use in flavor or fragrance formulations. It is addressed in flavor and fragrance safety standards such as FEMA (US) primarily as a compound to be noted rather than utilized due to its potent sulfurous and metallic sensory characteristics and absence of established safety data for consumer products.

(N-methyl-pyrryl-2)-methylthiol acetate possesses physico-chemical attributes typical of organosulfur acetates, including volatility and a distinct odor profile marked by sulfur and metallic notes. The molecular framework includes a methylated pyrrole ring linked to a methylthiol acetate moiety, affecting its chemical reactivity and sensory impact. Although explicit physicochemical data such as boiling point or solubility are not provided, its structure suggests moderate volatility and sensitivity to oxidation. These properties influence its handling and storage in laboratory conditions. The compound’s sensory characteristics reflect its chemical structure, contributing to pronounced burnt and metallic flavor impressions.
