Description
As a certified reference material (CRM), 2-(Benzylthio)-8,9,13b,14-tetrahydro-6H-[1,2,4]triazolo[5'',1'':2',3']pyrimido[4',5':4,5]pyrido[2,1-a]isoquinolin-6-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-(Benzylthio)-8,9,13b,14-tetrahydro-6H-[1,2,4]triazolo[5'',1'':2',3']pyrimido[4',5':4,5]pyrido[2,1-a]isoquinolin-6-one (CAS 344263-06-5), molecular formula C23H19N5OS and molecular weight 413.49 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(Benzylthio)-8,9,13b,14-tetrahydro-6H-[1,2,4]triazolo[5'',1'':2',3']pyrimido[4',5':4,5]pyrido[2,1-a]isoquinolin-6-one (C23H19N5OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
