5,6-Diamino-1,3-dimethyl-2-thioxo-2,3-dihydropyrimidin-4(1H)-one CAS 6501-96-8

Description

Compared with other compounds in its class, the molecular weight of 186.23 g/mol gives 5,6-Diamino-1,3-dimethyl-2-thioxo-2,3-dihydropyrimidin-4(1H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5,6-Diamino-1,3-dimethyl-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (CAS 6501-96-8) is a high-purity analytical reference standard with the molecular formula C6H10N4OS and a molecular weight of 186.23 g/mol.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 5,6-Diamino-1,3-dimethyl-2-thioxo-2,3-dihydropyrimidin-4(1H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.23 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.

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.
