Chemical Structure

Hydroxy-PEG9-Boc CAS 2055042-66-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 542.66 g/mol gives Hydroxy-PEG9-Boc distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Hydroxy-PEG9-Boc (CAS 2055042-66-3), a certified reference material (molecular formula C25H50O12, MW 542.66 g/mol) for analytical method development and quality control.

Structurally, Hydroxy-PEG9-Boc (C25H50O12) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 542.66 g/mol, it falls into the moderately-high-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.
