5-ethyl-3(or 2),4-dimethyl octahydro-4,7-methanoinden-5-ol

5-ethyl-3(or 2),4-dimethyl octahydro-4,7-methanoinden-5-ol is a bicyclic alcohol characterized by its complex molecular structure featuring a methanoinden backbone partially saturated through octahydro substitution. This compound exhibits a weak but distinct odor profile described as earthy with piney, green, resinous, and camphoraceous notes when evaluated at full concentration. It is also recognized under closely related synonyms that reflect minor variations in its nomenclature. Due to its chemical structure and sensory features, it is of interest for research in chemical odour profiling yet lacks direct application in perfumery or flavor manufacture. The compound can be referenced in controlled chemical databases such as PubChem though detailed sourcing information remains limited due to the specificity of its synthetic derivation or isolation. It primarily serves an informational role within chemical and sensory science domains.

This bicyclic alcohol does not occur widely in natural sources or biological systems and is mainly of synthetic origin. Its applications are restricted since it is not used in the formulation of fragrances or flavorings according to current standards. As such, it holds no official consumer product function and remains a compound primarily studied for informational purposes within chemical research. Regulatory frameworks such as REACH (EU) may document such substances but do not list it for commercial fragrance or flavor use. Its sensory profile, including low-level earthy and piney odors, suggests potential interest in odor characterization studies, though no practical utilization in consumer products has been established or recommended.

The molecular complexity of 5-ethyl-3(or 2),4-dimethyl octahydro-4,7-methanoinden-5-ol influences its physicochemical characteristics, notably its odor emission features. The compound contains multiple chiral centers and a saturated methanoinden ring system that contribute to its three-dimensional conformation. This conformation affects how the molecule interacts with olfactory receptors, producing a weak earthy and resinous aroma along with subtle camphoraceous and green notes. Its moderate volatility at ambient temperatures facilitates detection by sensory instruments, though the intensity remains low. Chemical stability under normal laboratory conditions is expected, supported by the lack of reported hazard classifications. These properties limit its practical handling considerations but present utility in detailed olfactory research contexts.
