Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 371.38 g/mol gives Z-Glu-OBzl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Z-Glu-OBzl (CAS 3705-42-8), a certified reference material (molecular formula C20H21NO6, MW 371.38 g/mol) for analytical method development and quality control.
Z-Glu-OBzl (C20H21NO6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
