Chemical Structure
Description
As a certified reference material (CRM), 1-(1-Ethyl-1H-indol-3-yl)-3-(3-hydroxypropyl)urea 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.
1-(1-Ethyl-1H-indol-3-yl)-3-(3-hydroxypropyl)urea (CAS 922850-01-9), molecular formula C14H19N3O2 and molecular weight 261.32 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-(1-Ethyl-1H-indol-3-yl)-3-(3-hydroxypropyl)urea is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 261.32 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.
