Chemical Structure

S-Acetyl-PEG3-C2-acid CAS 1421933-33-6 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 S-Acetyl-PEG3-C2-acid.

CATO supplies S-Acetyl-PEG3-C2-acid (CAS 1421933-33-6), a certified reference material (molecular formula C11H20O6S, MW 280.34 g/mol) for analytical method development and quality control.

Structurally, S-Acetyl-PEG3-C2-acid (C11H20O6S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 280.34 g/mol, it falls into the medium-molecular-weight range.

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.
