Abstract
[3859-41-4] C5H6O2 (MW 98.01) InChI = 1S/C5H6O2/c6-4-1-2-5(7)3-4/h1-3H2 InChIKey = LOGSONSNCYTHPS-UHFFFAOYSA-N (building block for the syntheses of cyclic and polycyclic compounds containing the cyclopentane ring) Physical Data: mp 149–151 °C. Solubility: sol H2O (5.5 g/100 g), DMF (20 g/100 g). Form Supplied in: yellow solid. Analysis of Reagent Purity: HPLC. Preparative Methods: the industrial production of 1,3-cyclopentanedione is based on methyl (E)-4-chloro-3-methoxy-2-butenoate.1 Other syntheses are based on norborn-2-ene2 or d-glucono-1,5-lactone.3 Further methods for the laboratory preparation have been reviewed.4 Handling, Storage, and Precautions: stable; this compound should be handled in a fume hood.
