Oxtriphylline(Secondary Standards traceble to USP) (CAS 4499-40-5), molecular formula C7H7N4O2C5H14NO and molecular weight 283.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Oxtriphylline(Secondary Standards traceble to USP) (C7H7N4O2C5H14NO) is characterized by an amino-acid-derived structure, an amide 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.
