Description

(3Z,5E)-2-Methyl-1,3,5-Undecatriene is a high-purity, unsaturated hydrocarbon with a specific geometric isomerism that is critical for its function as a flavor and fragrance intermediate. This compound matters for its role in synthesizing complex aroma chemicals, contributing green, waxy, or floral notes to fine fragrances and flavor formulations. It is primarily needed by R&D and production chemists in the flavor and fragrance, agrochemical, and specialty chemical industries seeking to create or modify specific organoleptic profiles.

Application

• Flavor & Fragrance (F&F) Intermediate: A key building block for the synthesis of advanced aroma chemicals and specialty odorants.
• Agrochemical Synthesis: Used as a precursor in the development of certain pheromones and other bioactive compounds.
• Organic Synthesis Research: Serves as a valuable diene component in Diels-Alder and other cycloaddition reactions for creating novel molecular structures.
• Specialty Polymer Modifier: Can be investigated for introducing specific unsaturated side chains into polymers to alter physical properties.

Quality Control

Our (3Z,5E)-2-Methyl-1,3,5-Undecatriene is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure high isomeric purity and chemical identity. Certificates of Analysis (COA) detailing purity, isomer ratio, and impurity profiles are provided to guarantee consistent performance in your applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place. Recommended storage temperature is 2-8°C to minimize degradation and polymerization. Due to its highly volatile nature, keep containers tightly sealed when not in use and away from heat and ignition sources.
