Chemical Structure
Description
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.
5,8-Dimethyl-[1,2,4]triazolo[4,3-a]quinoline-1-thiol (CAS 930396-22-8), molecular formula C12H11N3S and molecular weight 229.30 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5,8-Dimethyl-[1,2,4]triazolo[4,3-a]quinoline-1-thiol (C12H11N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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 229.30 g/mol, it falls into the medium-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
