Chemical Structure
Description
CATO supplies 7-(4-Fluorophenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-2-amine (CAS 338953-45-0), a certified reference material (molecular formula C11H8FN5, MW 229.21 g/mol) for analytical method development and quality control.
Structurally, 7-(4-Fluorophenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-2-amine (C11H8FN5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 229.21 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures 7-(4-Fluorophenyl)-[1,2,4]triazolo[1,5-a]pyrimidin-2-amine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
