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.
2-(5-((3,4-Dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyrazine (CAS 618427-38-6) is a high-purity analytical reference standard with the molecular formula C15H13Cl2N5S and a molecular weight of 366.27 g/mol.
Structurally, 2-(5-((3,4-Dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyrazine (C15H13Cl2N5S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 366.27 g/mol, it falls into the moderately-high-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.
