Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1,3-Bis(2,3,4,9-tetrahydro-1H-carbazol-3-yl)urea (CAS 1437794-63-2), a certified reference material (molecular formula C25H26N4O, MW 398.50 g/mol) for analytical method development and quality control.
The molecular framework of 1,3-Bis(2,3,4,9-tetrahydro-1H-carbazol-3-yl)urea (C25H26N4O) is characterized by a steroid core, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 1,3-Bis(2,3,4,9-tetrahydro-1H-carbazol-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.
