3-Ethyl-2-((2-(4-methylpiperidin-1-yl)-2-oxoethyl)thio)-3,5,6,7-tetrahydro-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidin-4-one CAS 483976-40-5

Description

3-Ethyl-2-((2-(4-methylpiperidin-1-yl)-2-oxoethyl)thio)-3,5,6,7-tetrahydro-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidin-4-one (CAS 483976-40-5) is a high-purity analytical reference standard with the molecular formula C19H25N3O2S2 and a molecular weight of 391.55 g/mol.

The molecular framework of 3-Ethyl-2-((2-(4-methylpiperidin-1-yl)-2-oxoethyl)thio)-3,5,6,7-tetrahydro-4H-cyclopenta[4,5]thieno[2,3-d]pyrimidin-4-one (C19H25N3O2S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
