12-(1H-Pyrazol-5-yl)-8-thia-1,10-diazatricyclo[7.4.0.0^{2,7}]trideca-2(7),3,5,9,11-pentaen-13-one CAS 318949-47-2

Description

Compared with other compounds in its class, the molecular weight of 268.29 g/mol gives 12-(1H-Pyrazol-5-yl)-8-thia-1,10-diazatricyclo[7.4.0.0^{2,7}]trideca-2(7),3,5,9,11-pentaen-13-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

12-(1H-Pyrazol-5-yl)-8-thia-1,10-diazatricyclo[7.4.0.0^{2,7}]trideca-2(7),3,5,9,11-pentaen-13-one (CAS 318949-47-2) is a high-purity analytical reference standard with the molecular formula C13H8N4OS and a molecular weight of 268.29 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 12-(1H-Pyrazol-5-yl)-8-thia-1,10-diazatricyclo[7.4.0.0^{2,7}]trideca-2(7),3,5,9,11-pentaen-13-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 268.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
