Chemical Structure

Poly(oxy-1,2-ethanediyl), .alpha.-(1-oxohexadecyl)-.omega.-hydroxy- CAS 9004-94-8 chemical structure

Description

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.

Poly(oxy-1,2-ethanediyl), .alpha.-(1-oxohexadecyl)-.omega.-hydroxy- (CAS 9004-94-8) is a high-purity analytical reference standard with the molecular formula C18H36O3 and a molecular weight of 300.48 g/mol.

Poly(oxy-1,2-ethanediyl), .alpha.-(1-oxohexadecyl)-.omega.-hydroxy- (C18H36O3) 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.
