Description

2-Methylcyclopropanecarboxylic Acid is a specialized organic compound featuring a cyclopropane ring substituted with a carboxylic acid group and a methyl group, offering unique steric and electronic properties. This structural motif makes it a valuable chiral building block and intermediate in advanced organic synthesis, particularly for introducing constrained, three-membered ring systems into target molecules. It is essential for research and development chemists in the pharmaceutical, agrochemical, and fine chemical industries seeking to create novel compounds with specific biological activity or material properties.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the synthesis of active pharmaceutical ingredients (APIs), especially those requiring conformationally restricted carboxylic acid derivatives.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides where the cyclopropane moiety can enhance biological activity and stability.
• Ligand and Catalyst Development: Acts as a precursor for creating specialized ligands used in asymmetric catalysis and metal-organic frameworks (MOFs).
• Fine Chemical Production: Employed in the manufacture of flavors, fragrances, and advanced materials that benefit from its distinct chemical structure.
• Academic and Industrial R&D: A crucial reagent for methodological development in organic chemistry, including ring-opening and functionalization studies.

Quality Control

Our 2-Methylcyclopropanecarboxylic Acid is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC, GC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment. We support cGMP compliance for pharmaceutical applications and can tailor specifications to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its nature as a strong acid/organic solvent, it should be stored separately from strong bases, oxidizing agents, and reactive materials.
