(1R,2R)-rel-trans-1,2-Cyclopentanediol(CAT: R045031) is a chiral diol with the molecular formula C₅H₁₀O₂, featuring two hydroxyl groups in a trans configuration on a cyclopentane ring. Appearing as a white crystalline solid, it is soluble in polar solvents such as water and alcohols. The defined stereochemistry of the (1R,2R) isomer makes it valuable as a building block in asymmetric synthesis, chiral ligand preparation, and the production of enantiomerically pure compounds. It is used in pharmaceuticals, agrochemicals, and fine chemical synthesis, where stereochemical control is crucial. Its rigid cyclic structure and functional groups allow for selective chemical modifications in research and industrial applications.
