Chemical Structure

m-PEG9-phosphonic acid CAS 2055016-25-4 chemical structure

Description

The occurrence of m-PEG9-phosphonic acid is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

m-PEG9-phosphonic acid (CAS 2055016-25-4), molecular formula C19H41O12P and molecular weight 492.50 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, m-PEG9-phosphonic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 492.50 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), m-PEG9-phosphonic 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.
