Polyethylene Glycol Monooleyl Ether (n=approx. 20) CAS 9004-98-2 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 Polyethylene Glycol Monooleyl Ether (n=approx. 20).

Polyethylene Glycol Monooleyl Ether (n=approx. 20) (CAS 9004-98-2) is a high-purity analytical reference standard with the molecular formula C58H116O21 and a molecular weight of 1149.53 g/mol.

Polyethylene Glycol Monooleyl Ether (n=approx. 20) (C58H116O21) 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.

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.
