Chemical Structure

Ethyl 2-(3-methyl-5-oxo-2-thioxoimidazolidin-1-yl)benzoate CAS 956587-20-5 chemical structure

Description

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.

Ethyl 2-(3-methyl-5-oxo-2-thioxoimidazolidin-1-yl)benzoate (CAS 956587-20-5) is a high-purity analytical reference standard with the molecular formula C13H14N2O3S and a molecular weight of 278.33 g/mol.

The molecular framework of Ethyl 2-(3-methyl-5-oxo-2-thioxoimidazolidin-1-yl)benzoate (C13H14N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, 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).

CATO manufactures Ethyl 2-(3-methyl-5-oxo-2-thioxoimidazolidin-1-yl)benzoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
