Description

Isopatchoulane CAS NO 3724-42-3 is a high-purity sesquiterpene hydrocarbon, a key isomer of patchoulane, valued for its unique woody and earthy aromatic profile. This compound is essential for creating sophisticated, long-lasting fragrance bases and is a critical intermediate in the synthesis of complex aroma chemicals. It is primarily sought by manufacturers in the flavors and fragrances, cosmetics, and fine chemical synthesis industries for premium product formulations.

Application

• Fragrance Compound Synthesis: A crucial building block for creating high-value, complex woody and ambery fragrance molecules.
• Premium Perfumery: Used as a core component in luxury perfumes, colognes, and personal care products to impart a distinctive, long-lasting earthy-patchouli character.
• Flavor Enhancement: Employed in trace amounts to add depth and complexity to certain specialty flavor profiles.
• Aromatherapy & Home Fragrance: Incorporated into essential oil blends, diffuser oils, and scented candles for its grounding and robust aromatic properties.
• Chemical Intermediate: Serves as a starting material or intermediate in organic synthesis for pharmaceuticals and other fine chemicals.
• Cosmetic Ingredient: Used in premium skincare and cosmetic formulations where its specific scent profile is desired.

Quality Control

Our Isopatchoulane is manufactured under strict quality management systems. Each batch is analyzed using advanced chromatographic and spectroscopic techniques (GC, GC-MS, NMR) to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical specifications. Our quality commitment aligns with standards relevant to the fragrance and flavor industry, including IFRA guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at 15-25°C. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize headspace in partially used containers. Keep away from heat, sparks, and open flame.
