4-Amino-5-((3,4-dimethylphenoxy)methyl)-4H-1,2,4-triazole-3-thiol CAS 301804-96-6

Description

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.

4-Amino-5-((3,4-dimethylphenoxy)methyl)-4H-1,2,4-triazole-3-thiol (CAS 301804-96-6), molecular formula C11H14N4OS and molecular weight 250.32 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Amino-5-((3,4-dimethylphenoxy)methyl)-4H-1,2,4-triazole-3-thiol (C11H14N4OS) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 4-Amino-5-((3,4-dimethylphenoxy)methyl)-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.
