Chemical Structure

3-4-6-Tri-O-benzyl-2-deoxy-D-galactopyranose CAS 94189-64-7 chemical structure

Description

The occurrence of 3-4-6-Tri-O-benzyl-2-deoxy-D-galactopyranose is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-4-6-Tri-O-benzyl-2-deoxy-D-galactopyranose (CAS 94189-64-7) is a high-purity analytical reference standard with the molecular formula C27H30O5 and a molecular weight of 434.52 g/mol.

Structurally, 3-4-6-Tri-O-benzyl-2-deoxy-D-galactopyranose (C27H30O5) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 434.52 g/mol, it falls into the moderately-high-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).

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.
