(1-(2,5-Dichlorophenyl)-1H-1,2,3-triazol-4-yl)methanamine (CAS 1248232-33-8), molecular formula C9H8Cl2N4 and molecular weight 243.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1-(2,5-Dichlorophenyl)-1H-1,2,3-triazol-4-yl)methanamine (C9H8Cl2N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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.
As a certified reference material (CRM), (1-(2,5-Dichlorophenyl)-1H-1,2,3-triazol-4-yl)methanamine 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.
