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.
CATO supplies 5-amino-12-methyl-6-thia-2,4,10,13-tetraazatricyclo[7.4.0.0³,⁷]trideca-1(9),2,4,7,12-pentaen-11-one (CAS 114794-03-5), a certified reference material (molecular formula C9H7N5OS, MW 233.25 g/mol) for analytical method development and quality control.
The molecular framework of 5-amino-12-methyl-6-thia-2,4,10,13-tetraazatricyclo[7.4.0.0³,⁷]trideca-1(9),2,4,7,12-pentaen-11-one (C9H7N5OS) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
