Chemical Structure
Description
CATO supplies (S)-2-methyl-2-((3-(oxiran-2-ylmethoxy)phenyl)sulfonyl)propan-1-ol (CAS 1889064-70-3), a certified reference material (molecular formula C13H18O5S, MW 286.34 g/mol) for analytical method development and quality control.
Based on its molecular formula C13H18O5S, (S)-2-methyl-2-((3-(oxiran-2-ylmethoxy)phenyl)sulfonyl)propan-1-ol contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 286.34 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.
