Chemical Structure

Thiol-PEG6-alcohol CAS 194425-46-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Thiol-PEG6-alcohol.

CATO supplies Thiol-PEG6-alcohol (CAS 194425-46-2), a certified reference material (molecular formula C12H26O6S, MW 298.40 g/mol) for analytical method development and quality control.

Thiol-PEG6-alcohol (C12H26O6S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
