Description

2-Methylundecanal Dimethylacetal is a high-purity specialty chemical intermediate and fragrance ingredient. This compound is valued for its unique aldehyde-acetal structure, which provides stability and a distinctive, powerful green, waxy, and citrus-like odor profile. It is primarily sought after by manufacturers in the fragrance and flavor industry for creating sophisticated scent compositions, as well as by fine chemical producers for use in organic synthesis.

Application

• Fragrance Formulation: A key building block in perfumery for imparting fresh, green, and citrus top notes in fine fragrances, personal care products, and household cleaners.
• Flavor Enhancement: Used in trace amounts to create or modify citrus, waxy, and aldehyde nuances in advanced flavor systems for food and beverages.
• Organic Synthesis: Serves as a protected aldehyde intermediate in multi-step synthesis for pharmaceuticals, agrochemicals, and other specialty organic compounds.
• Functional Fluids & Additives: Employed in the research and development of specialty additives for lubricants and functional fluids where specific chemical functionality is required.
• Aroma Chemical Production: Acts as a precursor or modifier in the synthesis of other complex aroma chemicals and odorants.
