474922-77-5
18:0 PEG3000 PE CAS 474922-77-5 chemical structure

Description

The occurrence of 474922-77-5 18:0 PEG3000 PE is closely related to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 474922-77-5 18:0 PEG3000 PE (CAS 474922-77-5), a certified reference material (molecular formula C133H263NO55PH4N, MW 2805.53 g/mol) for analytical method development and quality control.

Owing to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, 474922-77-5 18:0 PEG3000 PE is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 2805.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
