Description

The occurrence of 4-Aminophenyl-1-thio-β-D-galactopyranoside is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Aminophenyl-1-thio-β-D-galactopyranoside (CAS 29558-05-2) is a high-purity analytical reference standard with the molecular formula C12H17NO5S and a molecular weight of 287.33 g/mol.

Structurally, 4-Aminophenyl-1-thio-β-D-galactopyranoside (C12H17NO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 287.33 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
