Chemical Structure

m-PEG4-CH2-acid CAS 874208-84-1 chemical structure

Description

As a certified reference material (CRM), m-PEG4-CH2-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.

m-PEG4-CH2-acid (CAS 874208-84-1), molecular formula C11H22O6 and molecular weight 250.29 g/mol, is a CATO reference standard with documented purity and traceability.

m-PEG4-CH2-acid (C11H22O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
