Chemical Structure

m-PEG17-acid CAS 2346581-96-0 chemical structure

Description

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.

m-PEG17-acid (CAS 2346581-96-0) is a high-purity analytical reference standard with the molecular formula C36H72O19 and a molecular weight of 808.95 g/mol.

The molecular framework of m-PEG17-acid (C36H72O19) 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.

As a certified reference material (CRM), m-PEG17-acid 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.
