For derivatives glycoluril, glycoluril resins
The Uses of Glycoluril
Reactant involved in synthesis of:• ;Glycouril hexamers and monofunctionalized cucurbit[6]uril derivatives1,2,3• ;N-chloro compounds from trichloroisocyanuric acid4• ;Glycouril trimers5
The Uses of Glycoluril
Glycoluril is used as a reagent in the synthesis of acyclic cucurbit[n]uril molecular containers which can enhance the solubility and bioactivity of poorly soluble pharmaceuticals. Also used as a reagent in the synthesis of cucurbit[7]uril containers for targeted delivery of oxaliplatin to cancer cells.
