Chemical Structure
Description
(2R-4R)-2-[L-Xylo-tetrahydroxybut-1-yl]-1-3-thiazolidine-4-carboxylic acid (CAS 115184-30-0), molecular formula C8H15NO6S and molecular weight 253.27 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H15NO6S, (2R-4R)-2-[L-Xylo-tetrahydroxybut-1-yl]-1-3-thiazolidine-4-carboxylic acid contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 253.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
