Description

2-[2-(2,2,3-Trimethylcyclopent-3-En-1-Yl)Ethylidene]Valeraldehyde is a high-value, complex fragrance aldehyde known for its unique woody, amber, and leathery olfactory characteristics. This compound is prized for its ability to impart powerful and long-lasting scent profiles, enhancing the complexity and performance of fragrance formulations. It is primarily sought after by perfumers and manufacturers in the fine fragrance, personal care, and home care industries for creating sophisticated and distinctive aroma compositions.

Application

• Fine Fragrance Formulations: A key ingredient in premium perfumes, eau de toilettes, and colognes, providing rich woody-amber base notes.
• Personal Care Products: Used in scented body lotions, soaps, shampoos, and deodorants to deliver a luxurious and persistent fragrance.
• Home & Fabric Care: Incorporated into detergents, fabric softeners, and air fresheners for long-lasting scent retention on textiles and in the air.
• Functional Fragrances: Applied in products where odor-masking or a specific, stable scent profile is required.
• Flavor & Fragrance (F&F) Intermediates: Serves as a valuable building block for the synthesis of other complex aroma chemicals.

Quality Control

Our fragrance ingredients are produced and tested under strict quality management systems to ensure consistent organoleptic properties, purity, and stability. Each batch is analyzed using GC, GC-MS, and IR to verify identity and composition against established standards. Certificates of Analysis (COA) documenting purity, specific gravity, refractive index, and olfactory profile are available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) when in partially filled containers to maintain stability and prevent degradation.
