Chemical Structure

N,N'-1,2-Ethanediyl bis-hexadecanamide CAS 5518-18-3 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

N,N'-1,2-Ethanediyl bis-hexadecanamide (CAS 5518-18-3) is a high-purity analytical reference standard with the molecular formula C34H68N2O2 and a molecular weight of 536.92 g/mol.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, N,N'-1,2-Ethanediyl bis-hexadecanamide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 536.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
