(R)-ocean propanal

(R)-Ocean propanal, also known as (R)-helional and several other synonyms, is a chiral aldehyde with the chemical formula C11H12O3. This compound exhibits a predominantly floral odor profile, described as combining lily of the valley, cyclamen, and sweet fruity lemon notes. It belongs to a class of benzodioxole-containing aldehydes used as research chemicals in fragrance science. The molecular weight is approximately 192.21 g/mol. Structurally, it includes a methylenedioxyphenyl moiety combined with a methyl-substituted propanal group. Derivation typically involves synthetic organic processes relevant to the flavor and fragrance industry, although (R)-Ocean propanal is informational only and is not used commercially for fragrance or flavor applications. This material is indexed in chemical databases including PubChem, facilitating standard reference and structural verification.

(R)-Ocean propanal does not occur naturally and is synthesized for investigative uses in chemical research. Its applications are informational; it is not incorporated into fragrance or flavor formulations. The compound is notable for its floral-aldehydic sensory characteristics, making it a candidate for studies related to odorant structure-activity relationships. Its regulatory status under REACH (EU) and other regional standards emphasizes informational or research-only use, rather than commercial application. This serves purposes such as analytical calibration, reference standards, or academic study into odorous aldehydes but does not extend to direct consumer products.

(R)-Ocean propanal exhibits a boiling point near 286 to 287°C at atmospheric pressure, indicative of moderate volatility for aldehydes of its molecular weight. Its calculated partition coefficient (logP) of approximately 2.245 suggests moderate lipophilicity, influencing its solubility profile and interaction in biological or formulation environments. The compound is moderately soluble in alcohol and has an estimated water solubility around 342.6 mg/L at 25°C, reflecting partial hydrophilicity. Its vapor pressure is low (0.003 mmHg at 25°C), consistent with its boiling range and chemical structure. The reported flash point is about 117°C (244°F), indicating moderate flammability typical for aldehydic compounds. These properties guide handling, analytical procedures, and potential formulation considerations despite the compound's non-commercial use status.
