4-Methyl-5-[1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-4-yl]-4H-1,2,4-triazole-3-thiol CAS 477709-23-2

Description

4-Methyl-5-[1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-4-yl]-4H-1,2,4-triazole-3-thiol (CAS 477709-23-2) is a high-purity analytical reference standard with the molecular formula C16H14N6S and a molecular weight of 322.39 g/mol.

The molecular framework of 4-Methyl-5-[1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-4-yl]-4H-1,2,4-triazole-3-thiol (C16H14N6S) is characterized by a nitrogen-containing heterocyclic scaffold, 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.

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

As a certified reference material (CRM), 4-Methyl-5-[1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazol-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.
