Polyethylene glycol octadecyl ether CAS 9005-00-9 chemical structure

Description

As a certified reference material (CRM), Polyethylene glycol octadecyl ether 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.

Polyethylene glycol octadecyl ether (CAS 9005-00-9), molecular formula C20H42O2 and molecular weight 314.55 g/mol, is a CATO reference standard with documented purity and traceability.

Polyethylene glycol octadecyl ether (C20H42O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
