Chemical Structure

11-Mercaptoundecylhydroquinone CAS 185839-47-8 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.

11-Mercaptoundecylhydroquinone (CAS 185839-47-8) is a high-purity analytical reference standard with the molecular formula C17H28O2S and a molecular weight of 296.47 g/mol.

11-Mercaptoundecylhydroquinone (C17H28O2S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
