Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(3-Ethoxypropyl)-3-(1H-indol-3-yl)urea.
CATO supplies 1-(3-Ethoxypropyl)-3-(1H-indol-3-yl)urea (CAS 941878-95-1), a certified reference material (molecular formula C14H19N3O2, MW 261.32 g/mol) for analytical method development and quality control.
The molecular framework of 1-(3-Ethoxypropyl)-3-(1H-indol-3-yl)urea (C14H19N3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-(3-Ethoxypropyl)-3-(1H-indol-3-yl)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.
