benzyl ethyl carbinol

Benzyl ethyl carbinol, also known by its trivial name 1-phenyl-2-butanol, is an aromatic alcohol characterized by a molecular formula of C₁₀H₁₄O. It appears as a mild floral compound with fruity nuance, often described as reminiscent of hyacinth flowers. This compound is known under several synonyms, including alpha-ethylbenzeneethanol and 1-benzylpropyl alcohol. Its chemical features and sensory attributes place it within the class of phenyl-substituted alcohols commonly studied for their olfactory qualities. It can be sourced synthetically or identified as a minor natural constituent in some botanical extracts. A detailed description and chemical identifiers can be found on PubChem.

Benzyl ethyl carbinol occurs primarily in synthetic chemical contexts and is not widely reported as a major natural constituent in essential oils or botanical sources. Its floral and fruity olfactory notes have led to exploration for potential use in fragrance compositions where green and hyacinth-like aromas are desired. However, due to limited data on its safety and usage levels, it is designated for information purposes and is not commonly employed in commercial fragrances or flavorings. Regulatory frameworks such as REACH (European Union) provide registration data but do not establish specific usage guidelines for this compound, reflecting its niche status within the flavor and fragrance industry.

This compound features a relatively low vapor pressure of 0.046 mmHg at 25°C, indicating moderate volatility compatible with fragrance applications emphasizing subtle aroma release. Its boiling point ranges from 124 to 127°C under reduced pressure (25 mmHg), reflecting thermal stability within typical formulation processes. A specific gravity near unity (0.989 at 25°C) and estimated logP value of 2.367 suggest a balance between lipophilicity and hydrophilicity that may influence solubility in alcohol-based solvents and limited aqueous media (approximately 1885 mg/L water solubility at 25°C). The flash point of 100°C (converted from 212°F) highlights a relatively safe handling profile under standard laboratory conditions, supporting its investigative use in product development where non-flammable or moderately flammable solvents are required.
