Chemical Structure

1-(1H-Indol-3-yl)-3-mesitylurea CAS 941968-65-6 chemical structure

Description

The occurrence of 1-(1H-Indol-3-yl)-3-mesitylurea is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(1H-Indol-3-yl)-3-mesitylurea (CAS 941968-65-6), molecular formula C18H19N3O and molecular weight 293.36 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H19N3O, 1-(1H-Indol-3-yl)-3-mesitylurea contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 293.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
