Description

Compared with other compounds in its class, the molecular weight of 422.54 g/mol gives Polyquaternium 11 (20% in H2O) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Polyquaternium 11 (20% in H2O) (CAS 53633-54-8) is a high-purity analytical reference standard with the molecular formula C8H15NO2C4H10O4SC6H9NO and a molecular weight of 422.54 g/mol.

The molecular framework of Polyquaternium 11 (20% in H2O) (C8H15NO2C4H10O4SC6H9NO) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
