Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(4-((6,7-Dimethoxy-3,4-dihydroisoquinolin-1-yl)methyl)phenyl)-3-(2-nitrophenyl)urea (CAS 1024068-70-9), molecular formula C25H24N4O5 and molecular weight 460.48 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(4-((6,7-Dimethoxy-3,4-dihydroisoquinolin-1-yl)methyl)phenyl)-3-(2-nitrophenyl)urea (C25H24N4O5) is characterized by a flavonoid 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 1-(4-((6,7-Dimethoxy-3,4-dihydroisoquinolin-1-yl)methyl)phenyl)-3-(2-nitrophenyl)urea under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
