benzyl phenyl carbinol

Benzyl phenyl carbinol, also known by its trivial name (±)-1,2-diphenylethanol, is a secondary aromatic alcohol consisting of two phenyl groups attached to a hydroxy-substituted ethane backbone, with the molecular formula C14H14O. This compound is characterized by a clear appearance and possesses a floral odor reminiscent of orris root and violet notes, making it notable in fragrance chemistry. It is recognized under several synonyms such as 1,2-diphenyl-1-hydroxyethane and α-hydroxydibenzyl. Benzyl phenyl carbinol is sourced synthetically for use in perfumery applications rather than derived from natural extraction. The compound is registered in controlled chemical vocabularies with PubChem CID 94178, where comprehensive chemical information and structural data are available. Its floral scent profile and chemical stability contribute to its application as a fragrance component distinct from flavoring agents.

Benzyl phenyl carbinol does not commonly occur naturally but is synthesized for use in the fragrance industry. It is applied primarily as an odorant contributing floral nuances similar to orris and violet, which are prized in perfumery. Additionally, it functions as a fixer, enhancing the longevity and stability of fragrances. Despite these properties, it is important to note that benzyl phenyl carbinol is designated for informational purposes and is not used in flavors. Compliance with fragrance standards such as FEMA (US) guidelines informs its usage levels and safety evaluation. Its absence from flavor applications reflects regulatory distinctions and safety assessments relevant to the compound's chemical profile and sensory impact.

Benzyl phenyl carbinol presents as a moderately lipophilic molecule with an estimated logP of approximately 3. It has a molecular weight of 198.26 g/mol and a molecular formula C₁₄H₁₄O. The boiling point ranges narrowly between 308 and 309 °C at atmospheric pressure (760 mm Hg), indicating relatively low volatility under ambient conditions. Its vapor pressure at 25 °C is very low (about 0.0003 mm Hg), supporting its role as a fixative in fragrance blends. The compound is partially soluble in alcohol and has limited solubility in water. Its flash point is estimated at 128 °C (265 °F), suggesting moderate thermal stability during handling and formulation. These physicochemical attributes influence formulation strategies, dictating its compatibility with certain solvents and its effect on aroma longevity in finished products.
