Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Fluoro-3-{5h,6h,7h,8h,9h-[1,2,4]triazolo[4,3-a]azepin-3-yl}aniline (CAS 940242-26-2), molecular formula C13H15FN4 and molecular weight 246.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Fluoro-3-{5h,6h,7h,8h,9h-[1,2,4]triazolo[4,3-a]azepin-3-yl}aniline (C13H15FN4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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-Fluoro-3-{5h,6h,7h,8h,9h-[1,2,4]triazolo[4,3-a]azepin-3-yl}aniline 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.
