H-D-Glu(OBzl)-OBzl · p-tosylate (CAS 19898-41-0) is a high-purity analytical reference standard with the molecular formula C19H21NO4C7H8O3S and a molecular weight of 499.58 g/mol.
The molecular framework of H-D-Glu(OBzl)-OBzl · p-tosylate (C19H21NO4C7H8O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
