6-Hydroxy-11-(3-methoxyphenyl)-8-thia-3,5,10-triazatricyclo[7.4.0.0^{2,7}]trideca-1(9),2(7),5,10,12-pentaen-4-one CAS 674805-88-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Hydroxy-11-(3-methoxyphenyl)-8-thia-3,5,10-triazatricyclo[7.4.0.0^{2,7}]trideca-1(9),2(7),5,10,12-pentaen-4-one.

6-Hydroxy-11-(3-methoxyphenyl)-8-thia-3,5,10-triazatricyclo[7.4.0.0^{2,7}]trideca-1(9),2(7),5,10,12-pentaen-4-one (CAS 674805-88-0) is a high-purity analytical reference standard with the molecular formula C16H11N3O3S and a molecular weight of 325.34 g/mol.

6-Hydroxy-11-(3-methoxyphenyl)-8-thia-3,5,10-triazatricyclo[7.4.0.0^{2,7}]trideca-1(9),2(7),5,10,12-pentaen-4-one (C16H11N3O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
