Description

4,7,9-Megastigmatrien-3-One is a high-value, naturally derived aromatic ketone known for its potent and complex organoleptic profile. This compound is prized for its significant contribution to the characteristic flavor and aroma of tobacco, dried fruits, and certain teas. It is a critical ingredient for flavor and fragrance houses seeking to create authentic, sophisticated, and natural-smelling compositions. Industrial buyers in the flavor, fragrance, and advanced aroma chemical sectors rely on this material for its unique sensory properties and purity.

Application

• Tobacco Flavoring: A key component for enhancing and rounding off the natural, sweet, and dried-fruit notes in tobacco products and e-liquids.
• Fine Fragrance: Used as a heart note to impart rich, tobacco-leaf, and woody-ambery nuances in premium perfumes and colognes.
• Food & Beverage Flavors: Employed in the creation of complex flavor profiles for products like tea, dried fruits (figs, raisins), and certain spirits.
• Aroma Chemicals & Synergy: Serves as a building block or modifier in specialty aroma chemical blends to add depth and natural character.
• Cosmetic & Personal Care: Incorporated into scented lotions, soaps, and other personal care items where a warm, natural tobacco-type aroma is desired.
• Research & Development: Utilized in analytical chemistry and sensory science as a reference standard for tobacco and natural product analysis.

Quality Control

Our 4,7,9-Megastigmatrien-3-One is produced and tested to meet the stringent requirements of the flavor and fragrance industry. Every batch undergoes rigorous analytical testing, including chromatography and spectroscopic methods, to ensure identity, purity, and organoleptic quality. A Certificate of Analysis (COA) detailing purity, specific rotation (if applicable), and other critical parameters is provided with each shipment to guarantee consistency and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at controlled room temperature (15-25°C/59-77°F). Due to its highly volatile nature, keep containers tightly sealed when not in use to prevent evaporation and potential changes in concentration.
