Chemical Structure
Description
1-hexadecyl-3-[3-(hexadecylcarbamoylamino)-4-methyl-phenyl]urea 1-hexadecyl-3-[3-[[(hexadecylamino)-oxomethyl]amino]-4-methylphenyl]urea 697-88-1 A836650 (CAS 697-88-1), molecular formula C6H10BrCl2N and molecular weight 246.96 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to chlorine/bromine substitution, 1-hexadecyl-3-[3-(hexadecylcarbamoylamino)-4-methyl-phenyl]urea 1-hexadecyl-3-[3-[[(hexadecylamino)-oxomethyl]amino]-4-methylphenyl]urea 697-88-1 A836650 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.96 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.
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.
