Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3-Difluoro-4-iodobenzonitrile.
2,3-Difluoro-4-iodobenzonitrile (CAS 943830-91-9) is a high-purity analytical reference standard with the molecular formula C7H2F2IN and a molecular weight of 265.00 g/mol.
The molecular framework of 2,3-Difluoro-4-iodobenzonitrile (C7H2F2IN) is characterized by a nitrile group, fluorine/iodine substitution, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2,3-Difluoro-4-iodobenzonitrile 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.
