Bis-PEG17-acid CAS 2226897-74-9 chemical structure

Description

Bis-PEG17-acid (CAS 2226897-74-9) is a high-purity analytical reference standard with the molecular formula C38H74O21 and a molecular weight of 866.98 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Bis-PEG17-acid is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 866.98 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), Bis-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.
