rhodinyl butyrate

Rhodinyl butyrate, chemically known as 3,7-dimethyl-7-octen-1-yl butanoate, is an ester with the molecular formula C₁₄H₂₆O₂. This compound exhibits a distinctive floral odor characterized by fruity notes reminiscent of red rose, tropical berries, and geranium, combined with balsamic and powdery nuances, making it valuable for aroma applications. It is also described as having a matching floral flavor profile, supporting its dual use in taste and scent formulations. Known by several synonyms, including butyric acid esters of 3,7-dimethyl-7-octen-1-ol, rhodinyl butyrate is naturally found in geranium and is primarily utilized as a flavor and fragrance agent. Its detailed chemical structure and identity are recorded in authoritative sources such as PubChem, confirming its status within flavor chemistry.

Rhodinyl butyrate naturally occurs in geranium, contributing to the plant's characteristic aroma. It is widely employed in the flavor and fragrance industry to impart floral notes reminiscent of rose, geranium, and various tropical fruits such as apple, blackberry, cranberry, and pear. Due to its pleasant fruity and floral qualities, it is integrated into perfumes, personal care products, and multiple food flavorings. Its use conforms to safety standards established by FEMA (US) and JECFA (Global), which regulate concentration levels and applications to ensure consumer protection. These standards support its application for enhancing the sensory profile of baked goods, confectionery, beverages, and other consumables.

Rhodinyl butyrate's physical and chemical characteristics influence its suitability for formulation in flavor and fragrance products. It has a molecular weight of 226.36 g/mol and demonstrates moderate hydrophobicity with an estimated logP value of 5.225. The compound has a specific gravity ranging from 0.884 to 0.893 at 20°C and a very low vapor pressure of 0.002 mmHg at 25°C, indicating low volatility under ambient conditions. The flash point is measured at approximately 100°C (212°F), suggesting it is relatively stable to heat in typical processing scenarios. Its solubility profile indicates it is soluble in alcohol and slightly soluble in water at 0.5036 mg/L (estimated at 25°C), which informs its handling and blending characteristics. These combined properties contribute to its persistence and intensity in finished aroma compositions.
