peach cyclopentanone

Peach cyclopentanone, also known by its trade name Nectaryl, is a ketone characterized by the molecular formula C₁₅H₂₄O. This compound is recognized for its medium-strength fruity odor reminiscent of peach, apricot, and tropical lactonic notes, which contribute to its sophisticated sensory profile. Its odor character makes it a valuable ingredient in the creation of fine fragrances and perfuming agents. The compound is typically sourced through controlled synthesis and belongs to the class of pure odor and flavor compounds with ketonic functionality. Detailed chemical information about peach cyclopentanone is available in relevant chemical databases such as PubChem.

Peach cyclopentanone occurs primarily as a synthetic odorant in fragrance and perfume formulations. Its distinct fruity and lactonic scent profile lends itself to applications in fine fragrances, detergent powders, and toiletries, where it acts as a stable and long-lasting lactonic element. The compound's use is recognized and regulated under standards including IFRA (Global). Its stability in various media such as alcohol, soaps, and powder detergents supports its versatility across different consumer products. Although not utilized as a flavoring agent, it is highly regarded for creating fruity and woody olfactory impressions in complex aromatic blends.

Peach cyclopentanone is a ketone with a molecular weight of approximately 220.36 g/mol. It exhibits low vapor pressure (0.000367 mmHg at 25°C), indicating low volatility, and has an estimated logP value of around 4.34, highlighting its relatively high lipophilicity which influences its substantivity in formulations. The compound boils between 287 and 288°C at standard atmospheric pressure, consistent with its moderate volatility. It shows good solubility in alcohol and slight solubility in water (4.6 mg/L at 20°C), enabling broad compatibility in fragranced products. Stability assessments reveal robust behavior in alcoholic and powdered detergent environments, with moderate tolerance to acidic conditions and reduced stability in liquid bleach.
