ECHEMI Editorial Reference

15-crown-5 is a saturated organic heteromonocyclic parent that is cyclopentadecane in which the carbon atoms at positions 1, 4, 7, 10 and 13 have been replaced by oxygen atoms to give a crown ether. It is a crown ether and a saturated organic heteromonocyclic parent.
colourless liquid
15-Crown-5 is a crown ether generally used as a ligand in coordination chemistry because of its strong chelating property with certain alkali cations to form complexes. Some derivatives of 15-crown-5 are used as sensors and probes in different physical-chemical processes, phase-transfer reactions, and selective capture of ions for separation and transport.
Moderately toxic by ingestion, skin contact, and intraperitoneal routes. A skin and eye . When heated to decomposition it emits acrid smoke and irritating fumes
Dry it over 3A molecular sieves and distil it in a high vacuum. [Beilstein 19/12 V 252.]
