Chemical Structure

Polyethylene Glycol Monocetyl Ether CAS 9004-95-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 1123.49 g/mol gives Polyethylene Glycol Monocetyl Ether distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Polyethylene Glycol Monocetyl Ether (CAS 9004-95-9) is a high-purity analytical reference standard with the molecular formula C56H114O21 and a molecular weight of 1123.49 g/mol.

The molecular framework of Polyethylene Glycol Monocetyl Ether (C56H114O21) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
