5-[[4-(2-methoxyethoxy)phenyl]methylene]-2-thioxo-4-Thiazolidinone CAS 1439934-43-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-[[4-(2-methoxyethoxy)phenyl]methylene]-2-thioxo-4-Thiazolidinone.

5-[[4-(2-methoxyethoxy)phenyl]methylene]-2-thioxo-4-Thiazolidinone (CAS 1439934-43-6) is a high-purity analytical reference standard with the molecular formula C13H13NO3S2 and a molecular weight of 295.38 g/mol.

The molecular framework of 5-[[4-(2-methoxyethoxy)phenyl]methylene]-2-thioxo-4-Thiazolidinone (C13H13NO3S2) 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 its high hydrophobicity (logP), 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.

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.
