Polyoxyethylene Tridecyl Ether CAS 78330-21-9 chemical structure

Description

Polyoxyethylene Tridecyl Ether (CAS 78330-21-9) is a high-purity analytical reference standard with the molecular formula C37H76O13 and a molecular weight of 728.99 g/mol.

The molecular framework of Polyoxyethylene Tridecyl Ether (C37H76O13) 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.

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.

As a certified reference material (CRM), Polyoxyethylene Tridecyl Ether meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
