Cas no 139765-03-0 ((1R,2S)-2-methylcyclopropane-1-carbaldehyde)

(1R,2S)-2-Methylcyclopropane-1-carbaldehyde is a chiral cyclopropane derivative featuring a formyl functional group at the 1-position and a methyl substituent at the 2-position. Its stereospecific (1R,2S) configuration makes it a valuable intermediate in asymmetric synthesis, particularly for constructing biologically active molecules and fine chemicals. The strained cyclopropane ring enhances reactivity, enabling selective transformations, while the aldehyde group offers versatile functionalization potential. This compound is useful in pharmaceutical and agrochemical research, where precise stereochemistry is critical. High purity and well-defined stereochemistry ensure reproducibility in synthetic applications. Its stability under controlled conditions further supports its utility in complex organic synthesis.
