2-(5-((3-Chlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyridine CAS 618415-65-9

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-((3-Chlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyridine.

2-(5-((3-Chlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyridine (CAS 618415-65-9), molecular formula C16H15ClN4S and molecular weight 330.84 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 2-(5-((3-Chlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 330.84 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 2-(5-((3-Chlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
