Chemical Structure
Description
The occurrence of Poly(oxy-1,2-ethanediyl), .alpha.-(carboxymethyl)-.omega.-(4-isooctylphenoxy)-, sodium salt is closely related to a steroid core, 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.-(4-isooctylphenoxy)-, sodium salt (CAS 68015-73-6) is a high-purity analytical reference standard with the molecular formula C18H27O4Na and a molecular weight of 330.40 g/mol.
Structurally, Poly(oxy-1,2-ethanediyl), .alpha.-(carboxymethyl)-.omega.-(4-isooctylphenoxy)-, sodium salt (C18H27O4Na) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 330.40 g/mol, it falls into the moderately-high-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
