Chemical Structure
Description
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.
CATO supplies Ethyl 2-(2-(2-(2-(tosyloxy)ethoxy)ethoxy)ethoxy)acetate (CAS 118988-05-9), a certified reference material (molecular formula C17H26O8S, MW 390.45 g/mol) for analytical method development and quality control.
Ethyl 2-(2-(2-(2-(tosyloxy)ethoxy)ethoxy)ethoxy)acetate (C17H26O8S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
