4-(Sec-butyl)-5-(pyridin-4-yl)-4h-1,2,4-triazole-3-thiol CAS 239118-99-1

Description

4-(Sec-butyl)-5-(pyridin-4-yl)-4h-1,2,4-triazole-3-thiol (CAS 239118-99-1), molecular formula C11H14N4S and molecular weight 234.32 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-(Sec-butyl)-5-(pyridin-4-yl)-4h-1,2,4-triazole-3-thiol (C11H14N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 234.32 g/mol, it falls into the medium-molecular-weight range. 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.

As a certified reference material (CRM), 4-(Sec-butyl)-5-(pyridin-4-yl)-4h-1,2,4-triazole-3-thiol 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.
