Description

Isolongifolone is a high-purity sesquiterpene ketone valued for its unique woody, amber-like fragrance profile and its utility as a versatile chemical intermediate. This compound is essential for formulators and manufacturers seeking to create sophisticated, long-lasting aromatic notes or to synthesize more complex molecules. It is particularly relevant for the fragrance, flavor, and fine chemical synthesis industries, where consistent quality and reliable supply are paramount.

Application

• Fragrance & Perfumery: A key ingredient in high-end perfumes, colognes, and personal care products, providing a stable, woody-amber base note.
• Flavor Enhancement: Used in trace amounts to impart or modify woody, earthy nuances in specialty food and beverage flavorings.
• Aromatherapy & Home Scents: Incorporated into diffuser oils, candles, and incense for its grounding and persistent aromatic character.
• Chemical Synthesis: Serves as a valuable chiral building block or starting material in the synthesis of pharmaceuticals and other fine chemicals.
• Cosmetic Formulations: Employed in premium skincare and haircare products for its fragrance and potential soothing properties.
• Industrial Deodorants: Used in air fresheners and fabric conditioners to mask odors and provide a pleasant, long-lasting scent.
