682-30-4 KST-1A7519 [(2r,3s,4r)-5-(2,4-dioxo-3,4-dihydropyrimidin-1(2h)-yl)-3,4-dihydroxytetrahydrofuran-2-yl]methyl(3r,4s,5s,6r)-3-fluoro-4,5-dihydroxy-6-(hydroxymethyl)tetrahydro-2h-pyran-2-yl dihydrogen diphosphate(non-preferred name) CAS 682-30-4

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

682-30-4 KST-1A7519 [(2r,3s,4r)-5-(2,4-dioxo-3,4-dihydropyrimidin-1(2h)-yl)-3,4-dihydroxytetrahydrofuran-2-yl]methyl(3r,4s,5s,6r)-3-fluoro-4,5-dihydroxy-6-(hydroxymethyl)tetrahydro-2h-pyran-2-yl dihydrogen diphosphate(non-preferred name) (CAS 682-30-4), molecular formula C6H13O3P and molecular weight 164.14 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 682-30-4 KST-1A7519 [(2r,3s,4r)-5-(2,4-dioxo-3,4-dihydropyrimidin-1(2h)-yl)-3,4-dihydroxytetrahydrofuran-2-yl]methyl(3r,4s,5s,6r)-3-fluoro-4,5-dihydroxy-6-(hydroxymethyl)tetrahydro-2h-pyran-2-yl dihydrogen diphosphate(non-preferred name) (C6H13O3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 164.14 g/mol, it falls into the medium-molecular-weight range.

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.
