Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-chloro-5,7-dimethylpyrrolo[2,1-f][1,2,4]triazine (CAS 1554317-34-8), a certified reference material (molecular formula C8H16ClN3, MW 189.69 g/mol) for analytical method development and quality control.
The molecular framework of 4-chloro-5,7-dimethylpyrrolo[2,1-f][1,2,4]triazine (C8H16ClN3) is characterized by 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 4-chloro-5,7-dimethylpyrrolo[2,1-f][1,2,4]triazine 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.
