2-(2,3,4,6-Tetra-O-acetyl-β-D-galactopyranosyl)thiopseudourea Hydrobromide CAS 51224-13-6 chemical structure

Description

The occurrence of 2-(2,3,4,6-Tetra-O-acetyl-β-D-galactopyranosyl)thiopseudourea Hydrobromide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(2,3,4,6-Tetra-O-acetyl-β-D-galactopyranosyl)thiopseudourea Hydrobromide (CAS 51224-13-6) is a high-purity analytical reference standard with the molecular formula C15H22N2O9SHBr and a molecular weight of 487.32 g/mol.

Structurally, 2-(2,3,4,6-Tetra-O-acetyl-β-D-galactopyranosyl)thiopseudourea Hydrobromide (C15H22N2O9SHBr) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. 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 487.32 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
