Chemical Structure
Description
Structurally, Phenyl-2,3,4,6-tetra-O-acetyl-beta-D-galactopyranoside (C20H30O10) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 430.45 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).
Phenyl-2,3,4,6-tetra-O-acetyl-beta-D-galactopyranoside (CAS 2872-72-2), molecular formula C20H30O10 and molecular weight 430.45 g/mol, is a CATO reference standard with documented purity and traceability.
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.
As a certified reference material (CRM), Phenyl-2,3,4,6-tetra-O-acetyl-beta-D-galactopyranoside meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
