Chemical Structure

Acid-PEG7-t-butyl ester CAS 2134235-86-0 chemical structure

Description

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.

CATO supplies Acid-PEG7-t-butyl ester (CAS 2134235-86-0), a certified reference material (molecular formula C22H42O11, MW 482.56 g/mol) for analytical method development and quality control.

Acid-PEG7-t-butyl ester (C22H42O11) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
