sandal pentanol

Sandal pentanol, commonly known as Sandalore, is a synthetic organic compound classified as a scent ingredient with molecular formula C₁₄H₂₆O. It appears as a colorless liquid possessing a characteristic warm, woody sandalwood aroma with sweet and creamy accents. This compound is recognized under various synonyms including 3-methyl-5-(2,2,3-trimethyl-1-cyclopent-3-enyl)pentan-2-ol and pentamethyl cyclopent-3-ene butanol. Sandalore is extensively utilized in fragrance applications as a substitute for natural sandalwood oil, providing similar olfactory qualities with enhanced stability and substantivity. The compound is typically synthesized through organic chemical routes rather than being naturally extracted. Additional chemical data and definitions are available from authoritative sources such as PubChem. Sandalore's synthetic origin and olfactory properties make it an important material in modern perfumery and cosmetic formulations.

Sandal pentanol does not naturally occur in significant quantities but is synthetically produced as an aromatic substitute for sandalwood essential oil. Its main application is in fragrance formulations, where it imparts a rich, warm, woody sandalwood note. Due to the restricted availability and environmental concerns regarding natural sandalwood, Sandalore is valued as an effective replacement providing strong and sweet woody scents with excellent diffusivity and substantivity. It is used in various perfuming agents and cosmetic products under the guidelines of IFRA (Global), which governs fragrance safety and usage limits worldwide. Sandalore is also involved in fantasy blend fragrances and may contribute notes reminiscent of amyris, amber, and other botanical accords. Its versatility supports applications in personal care, fine fragrances, and household scent products.

Sandal pentanol is a colorless liquid with a molecular weight of approximately 210.36 g/mol and a molecular formula of C₁₄H₂₆O. It has a medium woody odor characterized as warm, sweet, and creamy sandalwood with significant substantivity lasting several hundred hours at full concentration. The compound exhibits a refractive index range of 1.47 to 1.476 at 20°C and a specific gravity between 0.895 and 0.903 at 25°C. Its low vapor pressure at room temperature (0.001 mmHg at 25°C) contributes to its longevity in fragrance applications. Sandalore is moderately soluble in alcohol and exhibits very limited water solubility. Its estimated log P around 4.6 reflects its lipophilic nature, favoring solubility in non-polar media. The boiling point reported under reduced pressure ranges from 95 to 98°C at 0.5 mm Hg, while its flash point is approximately 100°C (212°F), indicating relative stability and handling safety under typical use conditions.

Oral/Parenteral Toxicity:
oral-rat LD50 6700 mg/kg Together with Ebanol, and other sandalwood odourants it serves as an effective sandalwood replacement. Arcadi Boix Camps said of it in 1985 “It has a sweet, warm , strong, woody, santalaceous odor, which is immediately perceived on a blotter, and has a top note power about 50% greater than the essential oil of sandalwood, though it doesn’t last as long.”

	Notes:
IFRA FLAVOR REQUIREMENTS:
Due to the possible ingestion of small amounts of fragrance ingredients from their use in products in Categories 1 and 6, materials must not only comply with IFRA Standards but must also be recognized as safe as a flavoring ingredient as defined by the IOFI Code of Practice (www.iofi.org). For more details see chapter 1 of the Guidance for the use of IFRA Standards.
Recommendation for sandal pentanol flavor usage levels up to:
	not for flavor use.
