6-Hydroxy-11,13-dimethyl-8-thia-3,10-diazatricyclo[7.4.0.0^{2,7}]trideca-1(9),2(7),5,10,12-pentaen-4-one (CAS 290299-83-1) is a high-purity analytical reference standard with the molecular formula C12H10N2O2S and a molecular weight of 246.29 g/mol.
Structurally, 6-Hydroxy-11,13-dimethyl-8-thia-3,10-diazatricyclo[7.4.0.0^{2,7}]trideca-1(9),2(7),5,10,12-pentaen-4-one (C12H10N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 246.29 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
