santal penten-2-ol

Santal penten-2-ol is a bicyclic monoterpenoid alcohol with the molecular formula C14H24O and a molecular weight of approximately 208.34 g/mol. It presents as a colorless to pale liquid with a distinctive woody, spicy, and powdery odor profile, reminiscent of sandalwood note nuances. This compound is known by several chemical synonyms, including 3-methyl-5-(2,2,3-trimethyl-3-cyclopenten-1-yl)-3-penten-2-ol and the trade name isomohanol (Organica). Its chemical structure, featuring a cyclopentenyl ring substituted with methyl groups and a penten-2-ol moiety, contributes to its olfactory properties. Santal penten-2-ol is sourced through synthetic organic chemistry routes, typically designed for use as a fragrance material. For reliable chemical reference and data integration, it is cataloged in databases such as PubChem.

This compound is primarily employed as a fragrance agent in perfumery and related applications due to its woody and slightly spicy aromatic qualities. While naturally occurring analogues may exist in certain botanical sources, santal penten-2-ol is predominantly synthesized for industrial use. It complies with fragrance regulations and standards, notably including the IFRA (International Fragrance Association) Code of Practice (Global), which recommends usage levels up to 5% in fragrance concentrates. Commonly integrated into scent compositions, it enhances woody, powdery, and sandalwood accords. Although soluble in alcohols, it exhibits limited water solubility, which affects formulation considerations in aqueous-based products.

Santal penten-2-ol is a moderately lipophilic compound with an estimated logP value of 4.168, indicating substantial affinity for organic phases, which influences its behavior in fragrance formulations. It exhibits a boiling point near 282 to 283°C at standard atmospheric pressure, classifying it as relatively high boiling among fragrance alcohols. The specific gravity ranges from 0.89 to 0.91 at 25°C, consistent with a light, oily liquid. It has a very low vapor pressure of approximately 0.000399 mmHg at 25°C, suggesting low volatility under ambient conditions. The flash point is estimated at 213°F (approximately 100°C), requiring typical storage precautions. The compound is soluble in common aromatic solvents and alcohols but shows minimal aqueous solubility, approximately 6 mg/L at 25°C (estimated). Proper storage includes cool, dry environments away from light and heat sources, ensuring a shelf life of at least 12 months or longer if maintained correctly.
