Description

37860-51-8 Bis[2-(2-tosyloxyethoxy)ethyl] Ether Bis[2-[2-(p-toluenesulfonyloxy)ethoxy]ethyl] Ether T1493 Tetraethylene Glycol Bis(p-toluenesulfonate) Tetraethylene Glycol Di-p-tosylate (CAS 37860-51-8) is a high-purity analytical reference standard with the molecular formula C22H42O9S2 and a molecular weight of 514.69 g/mol.

Based on its molecular formula C22H42O9S2, 37860-51-8 Bis[2-(2-tosyloxyethoxy)ethyl] Ether Bis[2-[2-(p-toluenesulfonyloxy)ethoxy]ethyl] Ether T1493 Tetraethylene Glycol Bis(p-toluenesulfonate) Tetraethylene Glycol Di-p-tosylate contains 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 514.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
