Description
Compared with other compounds in its class, the molecular weight of 310.37 g/mol gives 4-(((3-Mercapto-5-(m-tolyl)-4H-1,2,4-triazol-4-yl)imino)methyl)phenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-(((3-Mercapto-5-(m-tolyl)-4H-1,2,4-triazol-4-yl)imino)methyl)phenol (CAS 478256-01-8), a certified reference material (molecular formula C16H14N4OS, MW 310.37 g/mol) for analytical method development and quality control.
The molecular framework of 4-(((3-Mercapto-5-(m-tolyl)-4H-1,2,4-triazol-4-yl)imino)methyl)phenol (C16H14N4OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-(((3-Mercapto-5-(m-tolyl)-4H-1,2,4-triazol-4-yl)imino)methyl)phenol 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.
