Description

2’’-Deoxy-5-[3-[[[(3’’,6’’-dihydroxy-3-oxospiro[isobenzofuran-1(3H),9’’-[9H]xanthen]-5-yl)amino]thioxomethyl]amino]-1-propynyl]uridine 5’’-(Tetrahydrogen Triphosphate) (CAS 137993-59-0) is a high-purity analytical reference standard with the molecular formula C33H29N4O19P3S and a molecular weight of 910.59 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, 2’’-Deoxy-5-[3-[[[(3’’,6’’-dihydroxy-3-oxospiro[isobenzofuran-1(3H),9’’-[9H]xanthen]-5-yl)amino]thioxomethyl]amino]-1-propynyl]uridine 5’’-(Tetrahydrogen Triphosphate) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 910.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 2’’-Deoxy-5-[3-[[[(3’’,6’’-dihydroxy-3-oxospiro[isobenzofuran-1(3H),9’’-[9H]xanthen]-5-yl)amino]thioxomethyl]amino]-1-propynyl]uridine 5’’-(Tetrahydrogen Triphosphate) 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.
