Structurally, 3-((4-Amino-2-methylpyrimidin-5-yl)methyl)-5-(2-((hydroxy(phosphonooxy)phosphoryl)oxy)ethyl)-4-methylthiazol-3-ium (C12H17N4O7P2SH) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 424.31 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
3-((4-Amino-2-methylpyrimidin-5-yl)methyl)-5-(2-((hydroxy(phosphonooxy)phosphoryl)oxy)ethyl)-4-methylthiazol-3-ium (CAS 136-08-3), molecular formula C12H17N4O7P2SH and molecular weight 424.31 g/mol, is a CATO reference standard with documented purity and traceability.
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.
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.
