1-isopropyl-4-thioxo-1,3,4,5,6,7-hexahydro-2h-cyclopenta[d]pyrimidin-2-one CAS 920158-33-4

Description

The molecular framework of 1-isopropyl-4-thioxo-1,3,4,5,6,7-hexahydro-2h-cyclopenta[d]pyrimidin-2-one (C10H14N2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

1-isopropyl-4-thioxo-1,3,4,5,6,7-hexahydro-2h-cyclopenta[d]pyrimidin-2-one (CAS 920158-33-4) is a high-purity analytical reference standard with the molecular formula C10H14N2OS and a molecular weight of 210.30 g/mol.

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.
