geranium nitrile

Geranium nitrile is a synthetic organic compound classified as a propanenitrile derivative with the molecular formula C₁₃H₁₉N. It appears as a liquid with a distinct floral odor reminiscent of rose geranium, combined with woody and sandalwood notes. Also known by synonyms including rose nitrile and sandatrile, this compound is valued in fragrance chemistry for contributing a medium-strength floral nuance. Detailed chemical structure information, including its InChIKey WHPKEUKLQUSZBC-UHFFFAOYSA-N, supports its identification in chemical databases such as PubChem. Geranium nitrile is predominantly synthesized for use in perfuming agents and is not naturally sourced from plant materials.

Geranium nitrile does not occur naturally but is a synthetic fragrance ingredient applied widely in perfumery to impart floral, geranium-like, woody, and sandalwood characteristics. It is recognized under the IFRA (Global) Code of Practice, which specifies usage limits ensuring consumer safety in fragrance concentrates. The compound is typically used at concentrations up to 3% in fragrance mixtures. Its medium odor strength and long substantivity, measured at 264 hours at full concentration, make it valuable for formulations requiring lasting floral notes. Besides their presence in perfumes, such compounds may also be found in cosmetic products for scent enhancement. Geranium nitrile does not have authorized use as a flavoring agent.

Geranium nitrile exhibits a molecular weight of approximately 189.3 g/mol and the formula C₁₃H₁₉N. It is a liquid at ambient temperatures with a specific gravity ranging from 0.942 to 0.952 at 20°C. The refractive index lies between 1.491 and 1.497 at the same temperature. It has a relatively high boiling point around 286 to 287°C at 760 mm Hg pressure and a low vapor pressure of 0.006 mm Hg at 25°C, indicating low volatility under standard conditions. The flash point is reported at 200°F (93.3°C), signifying moderate flammability risk. Geranium nitrile is soluble in alcohols and marginally soluble in water (estimated 3.562 mg/L at 25°C), underscoring selective solvent compatibility that influences its formulation in fragranced products. The estimated Log P value of 4.15 suggests considerable lipophilicity, compatible with oil-based perfume matrices.
