2-Mercapto-6,7-dihydro-3H-cyclopentapyrimidin-4(5H)-one CAS 35563-27-0

Description

The occurrence of 2-Mercapto-6,7-dihydro-3H-cyclopentapyrimidin-4(5H)-one is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-Mercapto-6,7-dihydro-3H-cyclopentapyrimidin-4(5H)-one (CAS 35563-27-0), a certified reference material (molecular formula C7H10N2OS, MW 170.23 g/mol) for analytical method development and quality control.

Structurally, 2-Mercapto-6,7-dihydro-3H-cyclopentapyrimidin-4(5H)-one (C7H10N2OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 170.23 g/mol, it falls into the medium-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.

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.
