Chemical Structure
Description
Structurally, 1,3-Butanediol, polymer with 1,1'-methylenebis[4-isocyanatobenzene], 2,2'-oxybis[ethanol] and 1,2-propanediol (C15H10N2O2C4H10O3C4H10O2C3H8O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 522.60 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
