Chemical Structure

Trt-PEG4-C2-acid (hydrate) CAS 1189873-11-7 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 Trt-PEG4-C2-acid (hydrate) (CAS 1189873-11-7), a certified reference material (molecular formula C30H36O6SH2O, MW 542.69 g/mol) for analytical method development and quality control.

Trt-PEG4-C2-acid (hydrate) (C30H36O6SH2O) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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.
