Chemical Structure
Description
The occurrence of 5-Methyl-3-((4-nitrophenyl)thio)-5H-[1,2,4]triazino[5,6-b]indole is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Methyl-3-((4-nitrophenyl)thio)-5H-[1,2,4]triazino[5,6-b]indole (CAS 4064-52-2), a certified reference material (molecular formula C16H11N5O2S, MW 337.36 g/mol) for analytical method development and quality control.
The molecular framework of 5-Methyl-3-((4-nitrophenyl)thio)-5H-[1,2,4]triazino[5,6-b]indole (C16H11N5O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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).
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.
As a certified reference material (CRM), 5-Methyl-3-((4-nitrophenyl)thio)-5H-[1,2,4]triazino[5,6-b]indole 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.
