Chemical Structure

Benzyl-PEG12-alcohol CAS 2218463-17-1 chemical structure

Description

CATO manufactures Benzyl-PEG12-alcohol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

Benzyl-PEG12-alcohol (CAS 2218463-17-1) is a high-purity analytical reference standard with the molecular formula C31H56O13 and a molecular weight of 636.77 g/mol.

The molecular framework of Benzyl-PEG12-alcohol (C31H56O13) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
