Usage

Uses

Used in Fragrance Industry:
Cyclopentadecanolide is used as a fixative in fragrance formulations for its capacity to extend the life of scents and improve their overall longevity. It is valued for its ability to blend and harmonize with other fragrance notes, contributing to a balanced and long-lasting aroma profile in a variety of perfumes, colognes, and scented products.
Used in Perfume Formulation:
Cyclopentadecanolide is used as a key ingredient in perfumes to provide a musky and woody base note, adding depth and complexity to the scent. Its stability and low potential for causing skin irritation make it a safe and reliable component in the creation of perfumes.
Used in Cologne Formulation:
In colognes, Cyclopentadecanolide serves to enhance the scent's staying power and enrich the overall fragrance experience. Its sweet, floral, and musky qualities complement the lighter, fresher notes typically found in colognes, creating a well-rounded and appealing scent.
Used in Other Scented Products:
Beyond traditional perfumes and colognes, Cyclopentadecanolide is utilized in a range of other scented products, such as candles, soaps, and body care items, to impart a pleasant and enduring fragrance while ensuring the product's scent remains consistent and stable over time.

ACTIVATED CARBOXYLATES FROM THE PHOTOOXYGENATION OF OXAZOLES; APPLICATION TO THE SYNTHESIS OF RECIFEIOLIDE, CURVULARIN AND MACROLIDES

Oxazoles may be used as masked forms of activated carboxylic acids since they readily form triamides on reaction with singlet oxygen.With 2-alkyl-4,5-diphenyloxazoles, the triamides formed on photooxygenation undergo selective nucleophilic attack at the acyl carbonyl derived from the 2-oxazole position.Using 2-(ο-hydroxyalkyl)-4,5-diphenyloxazoles as subsrates, the oxidation-acylation sequence may be employed for the synthesis of macrolides including (+/-)-recifeiolide and (+/-)-di-O-methylcurvularin.
