Chemical Structure
Description
CATO supplies 5'-O-TBDMS-N2-ibu-dG (CAS 85326-10-9), a certified reference material (molecular formula C20H33N5O5Si, MW 451.59 g/mol) for analytical method development and quality control.
The molecular framework of 5'-O-TBDMS-N2-ibu-dG (C20H33N5O5Si) is characterized by a flavonoid core, 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.
As a certified reference material (CRM), 5'-O-TBDMS-N2-ibu-dG meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
