Chemical Structure

3-Isobutyl-1H-1,2,4-triazol-5-thiol CAS 78201-10-2 chemical structure

Description

The molecular framework of 3-Isobutyl-1H-1,2,4-triazol-5-thiol (C6H11N3S) is characterized by a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

3-Isobutyl-1H-1,2,4-triazol-5-thiol (CAS 78201-10-2), molecular formula C6H11N3S and molecular weight 157.24 g/mol, is a CATO reference standard with documented purity and traceability.

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