Chemical Structure

2,5,8,11,14,17,20,23,26-Nonaoxaheptacosane CAS 25990-94-7 chemical structure

Description

2,5,8,11,14,17,20,23,26-Nonaoxaheptacosane (CAS 25990-94-7) is a high-purity analytical reference standard with the molecular formula C18H38O9 and a molecular weight of 398.49 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2,5,8,11,14,17,20,23,26-Nonaoxaheptacosane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
