Phenyl 4,6-O-Benzylidene-1-thio-α-D-mannopyranoside CAS 159407-19-9

Description

The occurrence of Phenyl 4,6-O-Benzylidene-1-thio-α-D-mannopyranoside is closely related to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Phenyl 4,6-O-Benzylidene-1-thio-α-D-mannopyranoside (CAS 159407-19-9), a certified reference material (molecular formula C19H20O5S, MW 360.42 g/mol) for analytical method development and quality control.

The molecular framework of Phenyl 4,6-O-Benzylidene-1-thio-α-D-mannopyranoside (C19H20O5S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
