Chemical Structure

4051-66-5 167726JT6B 1,3-Dioctadecylurea N,N'-Dioctadecylurea UNII-167726JT6B CAS 4051-66-5 chemical structure

Description

The molecular framework of 4051-66-5 167726JT6B 1,3-Dioctadecylurea N,N'-Dioctadecylurea UNII-167726JT6B (C37H76N2O) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

4051-66-5 167726JT6B 1,3-Dioctadecylurea N,N'-Dioctadecylurea UNII-167726JT6B (CAS 4051-66-5) is a high-purity analytical reference standard with the molecular formula C37H76N2O and a molecular weight of 565.01 g/mol.

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.
