(R)-(+)-α-Methylbenzyl isocyanate(CAT: R027085) is a chiral aromatic isocyanate widely used as a reagent and intermediate in asymmetric synthesis and chiral resolution. Featuring an (R)-configured α-methylbenzyl group attached to a highly reactive isocyanate (-NCO) functional group, it readily reacts with amines, alcohols, and other nucleophiles to form ureas, carbamates, and other heterocycles. Its enantiomeric purity makes it valuable for synthesizing optically active compounds, particularly in pharmaceutical research and development.
