3-{5h,6h,7h,8h,9h-[1,2,4]triazolo[4,3-a]azepin-3-yl}phenol (CAS 923256-33-1), molecular formula C13H15N3O and molecular weight 229.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-{5h,6h,7h,8h,9h-[1,2,4]triazolo[4,3-a]azepin-3-yl}phenol (C13H15N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
