Based on its molecular formula C12H24NO4SNa, 3-(N-Ethyl-m-toluidino)-2-hydroxypropanesulfonic acid sodium salt 82692-93-1 N-Ethyl-N-(2-hydroxy-3-sulfopropyl)-m-toluidine sodium salt Sodium 3-(N-ethyl-3-methylanilino)-2-hydroxypropanesulfonate Sodium N-ethyl-N-(2-hydroxy-3-sulfopropyl)-m-toluidine TOOS potassium 3-[ethyl(3-methylphenyl)amino]-2-hydroxypropane-1-sulfonate 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 301.38 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.
