CATO supplies 4-Nitro-Z-Gly-Cys(7-nitro-benzo[2,1,3]oxadiazol-4-yl)-Gly-OH (M-1590.0025) (CAS 152390-46-0), a certified reference material (molecular formula C21H19N7O11S, MW 577.48 g/mol) for analytical method development and quality control.
Structurally, 4-Nitro-Z-Gly-Cys(7-nitro-benzo[2,1,3]oxadiazol-4-yl)-Gly-OH (M-1590.0025) (C21H19N7O11S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 577.48 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.
