Description

3-Butenal (CAS NO 7319-38-2) is a highly reactive, unsaturated aldehyde that serves as a versatile building block in organic synthesis. Its conjugated system of a double bond and a carbonyl group makes it a valuable intermediate for creating more complex molecular structures. This compound is particularly sought after by research and development chemists in the pharmaceutical and fine chemical industries for synthesizing heterocycles, fragrances, and advanced polymer precursors.

Application

• Pharmaceutical Intermediate: A key starting material for the synthesis of various active pharmaceutical ingredients (APIs) and heterocyclic compounds.
• Fine Chemical Synthesis: Used in the production of specialty chemicals, including flavors, fragrances, and agrochemical intermediates.
• Polymer Chemistry: Acts as a monomer or cross-linking agent in the development of specialty polymers and resins.
• Organic Research: Employed in academic and industrial R&D for Diels-Alder reactions, Michael additions, and other carbon-carbon bond-forming transformations.
• Chemical Derivatization: Useful for modifying surfaces or biomolecules due to its reactive aldehyde functionality.

Quality Control

Our 3-Butenal is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, well-ventilated place, away from heat sources and oxidizing agents. Due to its highly volatile and easily oxidized nature, it is recommended for short-term storage at 2-8°C. Allow the container to reach ambient temperature before opening to minimize moisture ingress and degradation.
