Chemical Structure
Description
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.
CATO supplies N-octadecyl-n-[3-(triethoxysilyl)propyl]urea (CAS 106868-86-4), a certified reference material (molecular formula C28H60N2O4Si, MW 516.87 g/mol) for analytical method development and quality control.
Based on its molecular formula C28H60N2O4Si, N-octadecyl-n-[3-(triethoxysilyl)propyl]urea contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 516.87 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
