2-(5-((2,4-Dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyrazine CAS 573940-77-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(5-((2,4-Dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyrazine.

2-(5-((2,4-Dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyrazine (CAS 573940-77-9) is a high-purity analytical reference standard with the molecular formula C15H13Cl2N5S and a molecular weight of 366.27 g/mol.

2-(5-((2,4-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. Halogen substitution raises its density and boiling point; 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
