Description

3-Buten-2-One, 3-Methyl-4-(2,6,6-Trimethyl-1-Cyclohexen-1-Yl) is a high-purity, unsaturated ketone derivative of ionone, valued for its distinct woody and floral aroma profile. This compound is a critical intermediate and fragrance ingredient used in the synthesis of more complex aroma chemicals and in final fragrance formulations. It is primarily needed by manufacturers in the flavor and fragrance (F&F), cosmetic, and specialty chemical industries seeking to impart sophisticated olfactory notes.

Application

• Fragrance Formulation: A key building block and ingredient for creating woody, floral, and violet-like notes in fine perfumes, colognes, and personal care products.
• Flavor Enhancement: Used in trace amounts to contribute to complex fruity and berry flavor profiles in food and beverage applications.
• Chemical Synthesis: Serves as a versatile intermediate in organic synthesis for producing vitamin A analogs, carotenoids, and other terpenoid derivatives.
• Cosmetic Ingredients: Incorporated into lotions, soaps, and other cosmetic formulations as a fragrance component.
• Aroma Chemical Production: Used in the manufacture of other high-value ionone and damascone derivatives for the F&F industry.
• Household Products: Provides a stable, pleasant scent in detergents, fabric softeners, and air fresheners.

Quality Control

Our α-Ionone is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, isomer content, and olfactory purity. Our quality protocols are designed to meet the stringent requirements of the global flavor and fragrance industry.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, consider an inert atmosphere (e.g., nitrogen blanket) to preserve stability and organoleptic properties. Keep away from heat, sparks, and open flame.
