Chemical Structure
Description
As a certified reference material (CRM), 4-Amino-1-(2,3,5-tri-O-tert-butyldimethylsilyl-β-D-ribofuranosyl)imidazo[4,5-α]pyridine 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.
CATO supplies 4-Amino-1-(2,3,5-tri-O-tert-butyldimethylsilyl-β-D-ribofuranosyl)imidazo[4,5-α]pyridine (CAS 147212-86-0), a certified reference material (molecular formula C29H56N4O4Si3, MW 609.04 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-Amino-1-(2,3,5-tri-O-tert-butyldimethylsilyl-β-D-ribofuranosyl)imidazo[4,5-α]pyridine is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 609.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
