pyrazinylmethylthiol acetate

Pyrazinylmethylthiol acetate is a sulfur-containing organic compound belonging to the class of thioacetates with a pyrazinylmethyl substituent. It typically exhibits a mixture of sulfurous, toasted, nutty, and burnt cereal sensory characteristics, which define its flavor profile. The compound is also known under synonyms including pyrazinyl methyl thioacetate and pyrazinylmethylthiolacetate. It is referenced in chemical databases such as PubChem for structural and property data. Due to its intense sulfurous odor, pyrazinylmethylthiol acetate is primarily of academic or analytical interest rather than practical use. It is usually synthesized or isolated from pyrazine-related chemical pathways, rather than from natural extraction or commercial flavor production.

Pyrazinylmethylthiol acetate is not reported as a naturally occurring compound but is related structurally to pyrazine derivatives commonly found in roasted or cooked foods. Its notable sulfurous and burnt cereal aroma suggests relevance in understanding roasted flavor chemistry. However, regulatory frameworks such as FEMA (US) do not recognize this compound for use in flavors or fragrances, reflecting its current status as an informational substance. Its potential applications are confined to research settings focusing on sulfurous aroma compounds and mechanistic studies rather than consumer product formulation.

The compound’s sulfurous character arises from its thioacetate functional group attached to a pyrazinylmethyl moiety. These features impart chemical reactivity typical of sulfur esters, influencing volatility and stability under formulation conditions. Pyrazinylmethylthiol acetate generally exhibits moderate polarity combined with sulfur donor properties, which may affect its partitioning behavior in flavor matrices. Its strong roasted and burnt notes hint at a low odor threshold, though detailed thermodynamic or spectral data are limited. The chemical’s reactivity and sensory potency suggest caution in handling and analytical assessment but also limit practical use due to potential instability or off-flavor risks.
