Description

Methyl 3-butenoate is a versatile, highly volatile ester monomer with significant utility in organic synthesis. Its terminal alkene functionality makes it a valuable building block for creating more complex molecules through addition and polymerization reactions. This compound is particularly sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for its role in synthesizing active ingredients and functional materials.

Application

• Pharmaceutical Intermediates: Serves as a key synthon in the production of active pharmaceutical ingredients (APIs), particularly for molecules requiring a butenoate ester moiety.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators where its structure can be incorporated into the final active compound.
• Polymer & Resin Production: Acts as a co-monomer or cross-linking agent in the synthesis of specialty polymers, coatings, and adhesives, imparting specific flexibility or reactivity.
• Flavor & Fragrance Industry: Employed as a precursor for synthesizing esters that contribute to fruity or floral notes in fine fragrance and flavor compositions.
• Organic Synthesis Research: A fundamental reagent in academic and industrial laboratories for Diels-Alder reactions, Michael additions, and other carbon-carbon bond-forming transformations.
• Chemical Crosslinking: Utilized in formulations for UV-curable resins and other crosslinked network polymers due to its reactive double bond.

Quality Control

Our Methyl 3-Butenoate is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (IR, NMR), to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality parameters. We are committed to meeting the exacting standards required for research and industrial-scale synthesis.

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 highly volatile nature, ensure containers are kept tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
