Chemical Structure
Description
CATO supplies 3-(2-Thienylmethyl)-1,3-thiazolidine-4-carboxylic acid (CAS 1219381-73-3), a certified reference material (molecular formula C9H11NO2S2, MW 229.32 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H11NO2S2, 3-(2-Thienylmethyl)-1,3-thiazolidine-4-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 229.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
