Description

3-Methyl-4-Pentenoic Acid 97 is a high-purity unsaturated carboxylic acid characterized by its terminal alkene functionality. This compound is a valuable specialty chemical intermediate for synthesizing more complex molecules in fine chemical and pharmaceutical research. It is primarily sought by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and fragrance industries for constructing chiral centers and introducing reactive handles.

Application

• Pharmaceutical Intermediate: Serves as a key chiral building block for the synthesis of active pharmaceutical ingredients (APIs) and novel drug candidates.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators.
• Flavor & Fragrance Ingredient: Acts as a precursor for esters and lactones that contribute to complex scent and flavor profiles.
• Polymer Chemistry: Functions as a monomer or cross-linking agent in the production of specialty polymers and resins.
• Organic Synthesis Reagent: Employed in academic and industrial research for Michael additions, cyclization reactions, and other carbon-carbon bond-forming processes.
• Ligand & Catalyst Development: Useful for creating novel chiral ligands and metal-organic frameworks (MOFs) for asymmetric catalysis.
