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 cis-N,N-Dibenzyl-tetrahydro-selenolo[3,4-d]imidazol-2(3H)-one.
cis-N,N-Dibenzyl-tetrahydro-selenolo[3,4-d]imidazol-2(3H)-one (CAS 1346604-74-7), molecular formula C19H20N2OSe and molecular weight 371.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of cis-N,N-Dibenzyl-tetrahydro-selenolo[3,4-d]imidazol-2(3H)-one (C19H20N2OSe) 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 its high hydrophobicity (logP), 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), cis-N,N-Dibenzyl-tetrahydro-selenolo[3,4-d]imidazol-2(3H)-one 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.
