Description

2-Butenoic Acid, Sodium Salt, (2E)- is the sodium salt of the trans-isomer of 2-butenoic acid, commonly known as trans-crotonic acid. This high-purity chemical intermediate is valued for its role in organic synthesis and as a building block for more complex molecules. It is primarily sought by manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for applications requiring a consistent and reliable source of the crotonate anion.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and various drug candidates.
• Agrochemical Synthesis: Serves as a key precursor in the production of certain herbicides, fungicides, and plant growth regulators.
• Polymer Modification: Acts as a comonomer or modifier in specialty polymer and resin formulations to alter physical properties.
• Organic Synthesis: Employed in Michael addition reactions, esterifications, and other transformations to construct complex organic compounds.
• Research & Development: Utilized in chemical research for method development and as a standard in analytical laboratories.
• Cross-coupling Reactions: Can be used in palladium-catalyzed coupling reactions to introduce the crotonyl moiety into target molecules.
