Dihydro-2-methyl-3(2H)-thiophenone, identified by CAS number 13679-85-1, is a cyclic organosulfur compound belonging to the class of tetrahydrothiophenones. Characterized as a colorless to pale yellow liquid, it possesses a distinctively pungent, savory, and sulfurous aroma profile that is highly valued in specialized chemical formulations. Its molecular structure features a five-membered ring containing a sulfur atom and a ketone group, with a methyl substituent at the second position, contributing to its unique reactivity and sensory properties.
In industrial and research settings, this compound is recognized as a versatile building block and an essential component in the creation of complex aromatic profiles. Due to its volatility and specific odor threshold, it requires careful handling and storage in cool, well-ventilated environments, typically under inert gas to maintain its chemical stability. As a high-purity chemical raw material, it serves as a critical tool for chemists looking to synthesize sulfur-containing derivatives or develop sophisticated sensory products.
