Chemical Structure

HO-PEG16-OH CAS 4669-05-0 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 HO-PEG16-OH.

HO-PEG16-OH (CAS 4669-05-0) is a high-purity analytical reference standard with the molecular formula C32H66O16 and a molecular weight of 706.86 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, HO-PEG16-OH is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 706.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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), HO-PEG16-OH 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.
