Description

2-Ethyl-4-Pentenal is an unsaturated aliphatic aldehyde with a distinctive, reactive structure. This compound serves as a versatile chemical intermediate and flavor/fragrance precursor due to its α,β-unsaturated carbonyl functionality. It is primarily utilized by manufacturers in the flavor and fragrance, pharmaceutical, and specialty chemical synthesis industries.

Application

• Flavor and Fragrance Ingredient: Used as a building block for creating fruity, green, and aldehyde notes in perfumes and food flavorings.
• Pharmaceutical Intermediate: Serves as a key synthon in the synthesis of more complex molecules for active pharmaceutical ingredients (APIs).
• Organic Synthesis: Acts as a Michael acceptor or electrophile in various addition and condensation reactions.
• Polymer Modification: Employed in the production of specialty polymers and resins, where its double bond and aldehyde group can be utilized for cross-linking or functionalization.
• Agrochemical Synthesis: Used in the research and development of novel crop protection agents and pesticides.
• Research & Development: A valuable reagent for academic and industrial R&D in synthetic organic chemistry.

Quality Control

Our 2-Ethyl-4-Pentenal is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including GC, IR, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to store under an inert gas (e.g., nitrogen) and keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C for extended stability.
