Description

Cyclopentadecanone Oxime CAS NO 34341-05-4 is a high-purity, fine chemical intermediate of significant commercial interest. This compound serves as a critical building block in the synthesis of macrocyclic musks and other high-value fragrance ingredients. It is essential for manufacturers in the flavors and fragrances, pharmaceutical intermediates, and specialty chemical sectors seeking reliable, high-quality raw materials for complex syntheses.

Application

• Key Intermediate for Macrocyclic Musks: Primary use in the synthesis of high-value fragrance compounds like Exaltolide® (cyclopentadecanolide) and Muscone, prized for their clean, skin-like scent profiles.
• Fragrance and Perfumery Industry: Used in the production of premium perfumes, personal care products, and fine fragrances requiring long-lasting, non-allergenic musk notes.
• Pharmaceutical Research: Acts as a versatile synthon in medicinal chemistry for creating macrocyclic drug candidates and other complex molecular architectures.
• Specialty Chemical Synthesis: Employed in the manufacture of polymers, liquid crystals, and other advanced materials where a 15-membered ring structure is advantageous.
• Flavor Enhancers: Potential use in creating subtle, musky background notes for high-end flavor formulations.

Quality Control

Our Cyclopentadecanone Oxime is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from strong oxidizing agents.
