3-(4-hydroxy-4-methyl cyclohexyl) butanal

3-(4-hydroxy-4-methyl cyclohexyl) butanal is a synthetic organic compound characterized as an aldehyde with the molecular formula C11H20O2. This fragrance material appears as a clear substance and is primarily known for its mild floral odor reminiscent of lilac and muguet (lily of the valley). It is also referred to by the trivial name 3-(4-hydroxy-4-methylcyclohexyl)butanal, which is the same as its preferred IUPAC-derived name. The compound serves a specialized role as a fragrance agent in perfumery, where it imparts refined floral notes. Reference chemical data can be found through controlled vocabulary platforms such as PubChem. 3-(4-hydroxy-4-methyl cyclohexyl) butanal is synthesized chemically and not widely found in nature. It is used predominantly in fragrance compositions rather than flavor or therapeutic applications.

This compound does not commonly occur naturally but is valued in the fragrance industry for its floral scent profile resembling lilac and lily of the valley. Its application is focused on enhancing floral fragrance blends for personal care and household products. According to IFRA (Global) standards, its use is restricted to fragrance formulations. The compound is not approved for flavor use under IFRA guidelines. Its distinctive odor allows perfumers to create delicate, fresh floral accord notes that are challenging to replicate with natural extracts alone. These characteristics highlight its role as a niche ingredient for scent tailoring in cosmetic and fragrance product development.

3-(4-hydroxy-4-methyl cyclohexyl) butanal exhibits properties typical of medium-weight aldehydes. It has a molecular weight of approximately 184.28 g/mol and an estimated log P value around 1.5 to 1.8, indicating moderate hydrophobicity beneficial for volatility and skin compatibility. The boiling point ranges from 106 to 109°C at reduced pressure (0.6 mm Hg) and 279 to 280°C at atmospheric pressure (760 mm Hg), suggesting suitable thermal stability under typical fragrance processing conditions. Vapor pressure at 25°C is very low, approximately 0.000488 mmHg, supporting a controlled release of scent in use. The compound is soluble in alcohol and exhibits partial water solubility estimated at around 1460 mg/L at 25°C, which informs its formulation in both aqueous and solvent-based products. These attributes contribute to its performance as a stable and effective floral scent ingredient.
