Boc-Tyr(3,5-I2)-OSu (CAS 163679-35-4) is a high-purity analytical reference standard with the molecular formula C18H20I2N2O7 and a molecular weight of 630.17 g/mol.
The molecular framework of Boc-Tyr(3,5-I2)-OSu (C18H20I2N2O7) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. 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.
