Chemical Structure

Bis-CH2-PEG2-acid CAS 2250056-38-1 chemical structure

Description

CATO supplies Bis-CH2-PEG2-acid (CAS 2250056-38-1), a certified reference material (molecular formula C7H12O6, MW 192.17 g/mol) for analytical method development and quality control.

Bis-CH2-PEG2-acid (C7H12O6) contains a carbohydrate-derived structure. 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.
