Description
As a certified reference material (CRM), 2,3-Dimethoxy-11-(4-(trifluoromethyl)phenyl)-5,11,12,12a-tetrahydropyrazolo[3',4':4,5]pyrido[2,1-a]isoquinolin-8(6H)-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.
2,3-Dimethoxy-11-(4-(trifluoromethyl)phenyl)-5,11,12,12a-tetrahydropyrazolo[3',4':4,5]pyrido[2,1-a]isoquinolin-8(6H)-one (CAS 685108-22-9) is a high-purity analytical reference standard with the molecular formula C23H20F3N3O3 and a molecular weight of 443.42 g/mol.
The molecular framework of 2,3-Dimethoxy-11-(4-(trifluoromethyl)phenyl)-5,11,12,12a-tetrahydropyrazolo[3',4':4,5]pyrido[2,1-a]isoquinolin-8(6H)-one (C23H20F3N3O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
