Chemical Structure

1-Ethyl-3-(1H-indol-3-yl)-1-phenylurea CAS 941987-58-2 chemical structure

Description

The occurrence of 1-Ethyl-3-(1H-indol-3-yl)-1-phenylurea 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.

CATO supplies 1-Ethyl-3-(1H-indol-3-yl)-1-phenylurea (CAS 941987-58-2), a certified reference material (molecular formula C17H17N3O, MW 279.34 g/mol) for analytical method development and quality control.

Structurally, 1-Ethyl-3-(1H-indol-3-yl)-1-phenylurea (C17H17N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 279.34 g/mol, it falls into the medium-molecular-weight range. 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.

As a certified reference material (CRM), 1-Ethyl-3-(1H-indol-3-yl)-1-phenylurea meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
