Chemical Structure

Poly(ethylene Glycol) ~600 CAS 25322-68-3 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 Poly(ethylene Glycol) ~600.

Poly(ethylene Glycol) ~600 (CAS 25322-68-3), molecular formula H2O(C2H4O)n and molecular weight 62.07 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula H2O(C2H4O)n, Poly(ethylene Glycol) ~600 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 62.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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), Poly(ethylene Glycol) ~600 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.
