2-(4-Methylpiperidin-1-yl)-6-propyl-5-thioxo-5,6-dihydrothiazolo[4,5-d]pyrimidin-7(4H)-one (CAS 1334491-99-4), molecular formula C14H20N4OS2 and molecular weight 324.46 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(4-Methylpiperidin-1-yl)-6-propyl-5-thioxo-5,6-dihydrothiazolo[4,5-d]pyrimidin-7(4H)-one (C14H20N4OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 324.46 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.
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.
