Description

7-Methoxy-3,7-Dimethyl-Octanal is a high-purity aliphatic aldehyde derivative with a distinctive, powerful green and citrus-like odor profile. This compound matters as a versatile and potent fragrance intermediate, prized for its ability to impart fresh, natural, and long-lasting olfactory characteristics to complex scent formulations. It is primarily needed by manufacturers in the flavors and fragrances (F&F) industry, as well as by producers of fine chemicals and specialty aroma chemicals seeking to enhance product appeal.

Application

• Fragrance Ingredient: A key building block in the synthesis of high-value perfumes, colognes, and personal care products, contributing green, citrus, and floral nuances.
• Flavor Enhancer: Used in trace amounts to create or modify citrus and herbal flavor profiles in food and beverage applications.
• Aroma Chemical Synthesis: Serves as a critical intermediate for the production of more complex aroma molecules like lilial or lyral analogs.
• Household & Industrial Products: Incorporated into air fresheners, detergents, fabric softeners, and cleaning agents to provide a fresh, clean scent.
• Cosmetic Formulations: Used in soaps, shampoos, lotions, and other cosmetic products for its stable and appealing fragrance character.
• Functional Perfumery: Applied in functional products where scent stability and longevity under various pH and temperature conditions are required.

Quality Control

Our 7-Methoxy-3,7-Dimethyl-Octanal is produced under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for fragrance applications. Quality is verified through comprehensive analytical testing including GC, IR, and NMR. A Certificate of Analysis (COA) detailing purity, identity, and specific impurity profiles is provided with each shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in partially used containers to maintain stability and prevent degradation. Keep away from heat, sparks, open flames, and strong oxidizing agents.
