Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including alpha1,alpha4-Dicyano-alpha1,alpha4-Bis(1,1-Dimethylethyl)-2,3,5,6-Tetrafluoro-1,4-Benzenediacetonitrile.
CATO supplies alpha1,alpha4-Dicyano-alpha1,alpha4-Bis(1,1-Dimethylethyl)-2,3,5,6-Tetrafluoro-1,4-Benzenediacetonitrile (CAS 29097-86-7), a certified reference material (molecular formula C20H18F4N4, MW 390.38 g/mol) for analytical method development and quality control.
The molecular framework of alpha1,alpha4-Dicyano-alpha1,alpha4-Bis(1,1-Dimethylethyl)-2,3,5,6-Tetrafluoro-1,4-Benzenediacetonitrile (C20H18F4N4) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
