Chemical Structure
Description
CATO supplies 5-(4-Methylphenyl)-1,3,4-thiadiazol-2-amine (CAS 26907-54-0), a certified reference material (molecular formula C9H9N3S, MW 191.25 g/mol) for analytical method development and quality control.
The molecular framework of 5-(4-Methylphenyl)-1,3,4-thiadiazol-2-amine (C9H9N3S) 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.
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.
CATO manufactures 5-(4-Methylphenyl)-1,3,4-thiadiazol-2-amine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
