4-(5-((2-Chloro-6-fluorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyridine CAS 482640-08-4

Description

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.

4-(5-((2-Chloro-6-fluorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyridine (CAS 482640-08-4), molecular formula C16H14ClFN4S and molecular weight 348.83 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, fluorine/chlorine substitution, 4-(5-((2-Chloro-6-fluorobenzyl)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 348.83 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 4-(5-((2-Chloro-6-fluorobenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
