Chemical Structure
Description
The occurrence of Poly(oxy-1,2-ethanediyl), .alpha.-(carboxymethyl)-.omega.-(octadecyloxy)-, sodium salt is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Poly(oxy-1,2-ethanediyl), .alpha.-(carboxymethyl)-.omega.-(octadecyloxy)-, sodium salt (CAS 38815-90-6), molecular formula C22H43O4Na and molecular weight 394.57 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C22H43O4Na, Poly(oxy-1,2-ethanediyl), .alpha.-(carboxymethyl)-.omega.-(octadecyloxy)-, sodium salt contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 394.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
